Directions for question nos. 1-2: Eighty Five children went to amusement park where they could ride on merry -go-round roller coaster and Ferris wheel .It was known that 20 of them have took all three rides and 55 of them have taken at least two of the three rides. Each ride cost Rs.1 and the total receipt of the amusement park was Rs.145.

1) How many children did not try any of the rides. ?

A) 5 B) 10 C) 15 D) 20

Ans. 15.

20 kids * 3 rides = Rs. 60

(55-20=)35 kids * 2 rides = Rs. 70

60 + 70 = Rs. 130

So, Rs. (145 - 130 = ) 15 are left for the other (85 - 55 = ) 30 kids . so only 15 of them can take a ride and rest 15 will be left out.

145 rides were taken. 20 of them took all three, i.e. Rs. 60 were spent, so 145-60= Rs. 85 are left for the others. Total kids were 85, so rest were 65. out of these 65,

2) How many children took exactly one ride?

A) 5 B) 10 C) 15 D) 20

Ans. 15

A) 8

B) 12

C) 16

D) 20

Ans. 12.

Consider the top city, the following are the 3 routes possible, starting from the leftmost edge. Since there are 3 edges emanating from each city and the figure is perfectly symmetrical, these 3 routes are possible from each edge, hence for any given city, the total number of routes = 4 * 3 = 12.

d) const_cast

Ans. b

6.

class professor {};

class teacher : public virtual professor {};

class researcher : public virtual professor {};

class myprofessor : public teacher, public researcher {};

Referring to the sample code above, if an object of class "myprofessor" were created, how many instances of professor will it contain?

a) 0

b) 1

c) 2

d) 3

e) 4

Ans. b , here professor will be called a virtual base class since teacher and researcher derive from it virtually. This is used in multiple inheritance as shown here. If professor was not inherited virtually then there would be 2 instances of professor in the object of myprofessor.

7.

string somestring ;

Which of the following choices will convert a standard C++ string object "somestring" to a C string?

a) Copy.somestring () ;

b) somestring.c_str ()

c) &somestring [1]

d) std::cstring (somestring)

e) (char *) somestring

Ans. b

8.

class ba***

{

int x;

public:

void setx(int y) {x=y;}

};

class derived : ba*** {};

What is the access level for the member function "setx" in the class "derived" above?

a) private

b) local

c) global

d) public

e) protected

Ans. a

E) Table of Member Access Privileges

Access in Base Class Base Class Inherited as Access in Derived Class

Public Protected Private Public Public Protected No access1

Public Protected Private Protected Protected Protected No access1

Public Protected Private Private Private Private No access1

1 Unless friend declarations within the base class explicitly grant access.

So, the highest member accessibility is defined by the way a class is inherited, if it is inherited privately, then the highest member accessibility will be private. Default inheritance is private.

9.

class Alpha {

public:

char data[10000];

Alpha();

~Alpha();

};

class Beta {

public:

Beta() { n = 0; }

void FillData(Alpha a);

private:

int n;

};

How do you make the above sample code more efficient?

a) If possible, make the constructor for Beta private to reduce the overhead of public constructors.

b) Change the return type in FillData to int to negate the implicit return conversion from "int" to "void".

c) Make the destructor for Alpha virtual.

d) Make the constructor for Alpha virtual.

e) Pass a const reference to Alpha in FillData

Ans. e. since u r passing a reference hence a new array will not be created in memory, whereas if u pass by value, then an array of 10000 chars will be created. Passing by reference only creates an alias for the original parameter (i.e., it points to the original parameter) and is same as passing by address, the only difference is that it can be used like an object instead of as a pointer, i.e., if param is &a, then u will write a.member, whereas if param is *a then u will write a->member.

10.

class Foo {

int x;

public:

Foo(int I);

};

If a class does not have a copy constructor explicitly defined one will be implicitly defined for it. Referring to the sample code above, which one of the following declarations is the implicitly created copy constructor?

a) Foo(Foo *f);

b) Foo(Foo &f);

c) Foo(const Foo *f);

d) Foo(const Foo &f);

e) Foo(int);

Ans. d. copy constructor takes an arg of its own type which is passed by ref and which should not be changed hence it is const

11.

class HasStatic {

static int I;

};

Referring to the sample code above, what is the appropriate method of defining the member variable "I", and assigning it the value 10, outside of the class declaration?

a) HasStatic I = 10;

b) int static I = 10;

c) static I(10);

d) static I = 10;

e) int HasStatic::I = 10;

Ans. e

12.

class X

{

private:

int a;

protected:

X(){cout<<"X constructor was called"< ~X(){cout<<"X destructor was called"<};

Referring to the code above, which one of the following statements regarding "X" is TRUE?

a) X is an abstract class.

b) Only subclasses of X may create X objects.

c) Instances of X cannot be created.

d) X objects can only be created using the default copy constructor.

e) Only friends can create instances of X objects.

Ans. b. instances of X can be created only inside its subclasses.

13.

class Foo {

const int x;

protected:

Foo(int f);

~Foo();

};

Foo f;

Referring to the sample code above, why will the class declaration not compile?

a) The variable x is const.

b) The destructor is protected.

c) The destructor is not public.

d) The constructor is protected.

e) There is no default constructor.

Ans. e. if u don't specify a constructor for a class, then the compiler generates the default constructor for u, but if u specify a constructor apart from the default constructor, then u must give the default constructor also, but only if u r creating an object which uses the default constructor. i.e., the following code is perfectly fine

class Foo {

public:

Foo(int f){}

~Foo(){}

};

Foo f(0);

But if u try to create an object of Foo like this

Foo f;

then this will give compiler error because there is no default constructor available.

14.

class Foo {

public:

Foo(int i) { }

};

class Bar : virtual Foo {

public:

Bar() { }

};

Bar b;

Referring to the above code, when the object 'b' is defined, a compiler error will occur. What action fixes the compiler error?

a) Adding a virtual destructor to the class Bar

b) Adding a constructor to Bar which takes an int parameter

c) Adding "Foo()" to the Bar constructor

d) Adding a copy constructor to the class Foo

e) Adding "Foo(0)" to the Bar::Bar initializer list

Ans. e

15. Which one of the following describes characteristics of "protected" inheritance?

a) The base class has access only to the public or protected members of the derived class.

b) The derived class has non-public, inheritable, access to all but the private members of the base class.

c) The derived class has access to all members of the base class.

d) The private members of the base class are visible within the derived class.

e) Public members of the derived class are privately accessible from the base class.

Ans. b

16. The "virtual" specifier in a member function enables which one of the following?

a) Monmorphism

b) Late binding

c) Metamorphism

d) Solomorphism

e) Inheritance

Ans. b. consider a base class B having a virtual function Foo, and a class D derived from this class also having a function Foo. Then when u create an object of a derived class, say dobj, and a ptr to base class, say pb, and point pb to dobj by saying pb = &dobj, and then call pb->Foo then the correct version of Foo will be called, i.e., the version in D will be called becz the object is of type D. this is called late binding, i.e., deferring the decision of calling which version of Foo until runtime since at compile time the type of object to which pb points may not be known.

class B {public: virtual void Foo(){cout<<"base";}};

class D : public B {public: virtual void Foo(){cout<<"derv";}};

D dobj;

B *pb;

pb = &dobj;

pb->Foo();

the output will be 'derv'.

If Foo was not declared virtual in base class B , then the output would have been 'base'.

17.

class X

{

public:

int x;

static void f(int z);

};

void X::f(int y) {x=y;}

What is the error in the sample code above?

a) The class X does not have any protected members.

b) The static member function f() accesses the non-static z.

c) The static member function f() accesses the non-static x.

d) The member function f() must return a value.

e) The class X does not have any private members.

Ans. c

18.

template class Obj {

T my_t;

X my_x;

public:

Obj(T t, X x) : my_t(t), my_x(x) { }

};

Referring to the sample code above, which one of the following is a valid conversion operator for the type T?

a) T operator T () { return my_t; }

b) T operator(T) const { return my_t; }

c) operator(T) { return my_t; }

d) T operator T (const Obj &obj) { return obj.my_t; }

e) operator T () const { return my_t; }

Ans. e.

this will be used for casting objects of type Obj to type T

class Myclass{};

template class Obj {

T my_t;

X my_x;

public:

Obj(T t, X x) : my_t(t), my_x(x) { }

operator T () const { return my_t; }

operator X () const { return my_x; }

};

void main()

{

Myclass mt;

### C – Questions placement papers QUARK

C - Questions

1. What is the output of the following code

main()

{

printf("Hello %d",printf("QUARK test? "));

}

a. Compile time error.

b. Hello QUARK test?

c. Run time error.

d. None of the above.

e. Quark Test ?Hello.

Ans. d. the output is QUARK test? Hello 12

This is because the evaluation of the parameters in a function call is done from right to left, becz the parameters were passed via a stack hence the first parameter (the leftmost one) is at the bottom of the stack and the rightmost parameter (if it is an expresseion, it will be evaluated before putting it on the stack) is on the top of the stack, hence while popping the parameters from the stack, the function printf (or any other function) gets them in the reverse order, i.e., from right to left, hence the statement printf("Quark test? ") gets evaluated first while pushing it as a parameter on to the stack, and then the statement printf("Hello %d") is executed. The '12′ is the result of the return of printf("Quark test? ") which returns the number of characters printed.

2.) Out put of the following code is

main()

{

int i,j,A;

for (A = -1;A<=1; A++)

printf("%d\t",!!A);

}

main()

{

int i=255;

printf("%d\t",++(i++));

}

a. Compilation error

b. Runtime error

c. 256

d. 0

e. None of the above

Ans. Compile Time Error 'Lvalue Required

4) What shall be the output of the following code?

main()

{

char i = 'a';

printf("%c \t %c \t", i ,(++i));

}

a. a b

b. Compile time error

c. b b

d. a a

e. 65 66

Ans. b b

5) What shall be the output of the following code?

main() {

int i,j;

printf("QUARK %s\n",main());

}

a. Compilation error.

b. Run-time error

c. Continuous scrolling Quark on the screen.

d. None of the above.

Ans. There is nothing on the screen and prog waits till the memory lasts and then out of memory run time error, so ans is b.

6) What shall be the output of the following code ?

#define f(x) x*x*x

main(){

printf("\n%d",f(2+2));

}

a. 8

b. 64

c. 10

d. 12

Ans. f(2+2) will expand to 2+2*2+2*2+2

= 2+4+4+2

= 12

7) What shall be the output of the following code ?

main()

{

void fun1(void *);

char a[] = "quark";

void *temp;

temp = a;

fun1(temp);}

void fun1(void *temp1 )

{

int t1 = 0;

while(*((char*)temp1+ t1++ )!='\0′) {

printf("%c",*((char*)temp1 + t1));

}

}

a. Compilation error

b. ark

c. quark

d. uark

Ans, uark

8. What will be the out put of the following code?

void main()

{ int x=3;

printf("%d\t %d",x>>1, x<<3);

}

a. 1 and 4

b. 1 and 24

c. 1 and 27

d. None of the above

Ans. 1 and 24

This is because 3 in binary is 00000000 00000011 in two bytes (integer). Again, the right to left evaluation rule of parameters is applicable and so x<<3 gets executed first, it means left shift 3 times, but this operator does not change the value of x itself, it simply returns a value, so x retains its value after this operation has been carried out, so we get 00000000 00011000 which is 24, so 24 is pushed onto the stack, and then x>>1, right shift 1, 00000000 00000011, which is 1 in decimal, so 1 is pushed onto the stack, then printf("%d\t %d") gets executed displaying 1 24.

9. What will be the result of the following code?

int *x;

x =(int *) 15;

a. Compilation error

b. Compiles but gives a runtime error

c. Absolute location 15 in the memory space shall be assigned to pointer x;

e. Location 15 contains the address to an integer.

Ans d

10. Which of the following functions cannot be called from another file?

a. const void func(){ ……..}

b. extern void func(){………}

c. void func(){………}

d. static void func(){……….}

Ans. static

11. What will be the out come of the following code?

#include

int * func(){

static int x=0;

x++; return &x;

}

int main()

{

int * y = func();

printf("%d",(*y)++);

func();

printf("%d\n",*y);

return 0;

}

a. Compilation error.

b. Prints 1 and 3

c. Prints 1 and 3 but it is not good practice.

d. Prints 1 and 1

e. The code will not execute properly because y points to a variable whose life span is limited to execution of the function func();

Ans. Prints 1 and 3 but it is not a good practice

12. Referring to the above code , which of the following would be the correct

implementation for myFunc ?

char *format = "%d";

int main()

{

int x;

myFunc(scanf,&x);

printf("%d\n",x);

return(0);

}

a. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,&x);}

b. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,*x);}

c. void myFunc(int*y(const char*,…),int *x) {(*y)(format,&x);}

d. void myFunc(*(int y(const char*,…)),int *x) {(*y)(format,x);}

e. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,x);}

13. What shall be the output of the following C code?

void main()

{

unsigned int x= -1;

int y =0;

if(y<=x) printf("A is true\n");

if (y = =(x = -10)) printf("B is true\n");

if ((int) x>=y) printf("C is true\n");

}

a. A is true.

b. B is true.

c. C is true.

d. None of the above.

Ans. A is true because x contains -1, i.e., in binary it is ffff, i.e., all 1s, so being unsigned, all 1s are interpreted as the value 65535 and not as -1 (however, all 1s are interpreted as -1 if it is just an int), hence y<=x returns true.

14. In the following code what is the correct way to increment the variable ptr to

point to the next member of the array

union intfloat

{

int intArray[ 5];

float floatArray[ 5];

};

union intfloat arr[20];

void *ptr =arr;

a. ++(int*)ptr;

b. ptr = ptr+5;

c. ptr = ptr +sizeof(*ptr);

d. ptr = ptr+sizeof(intfloat.floatArray);

e. ptr = (void*)((union intfloat*)ptr +1);

Ans. e. ptr = (void*)((union intfloat*)ptr +1);

15.What shall be the output of the following program?

#define PRINTXYZ(x,y,z) printf (#x "=%d\t" #z "=%d\n", x, y)

void main() {

int x, y, z;

x=0; y=1; z=2;

x || ++y ||++z;

PRINTXYZ(x,y,z);

++x || ++y && ++z;

PRINTXYZ(x,y,z);

++x && ++y || ++z;

PRINTXYZ(x,y,z);

}

a. Compilation error.

b. Runtime error.

c.

x=0 z=2

x=1 z=3

x=2 z=4

d.

x=0 z=2

x=1 z=2

x=2 z=3

e. None of the above.

Ans. d.

16. What shall be the output of the following code ?

main()

{

printf("%d %d", sizeof(NULL), sizeof(""));

}

a. 1 and 0.

b. 0 and 1

c. 2 and 1

d. 4 and 1

e. None of the above

Ans. Depends on the machine and compiler. Actually it is the sizeof(int) and sizeof(char) as a string is stored as a char array terminated with 0, so sizeof("") gives 1, whereas sizeof("adsf") gives 5 (including the terminating 0). So in TurboC we get c as the answer, on VC we get d as the answer, so I guess e is the ans, i.e., None of the above.

17. What shall be the output of the following code?

int *check ( int,int);

void main()

{int c,d;

c = check(11,29);

d= check(20,30);

printf("\nc=%u",c);

}

int * check(int i,int j )

{

int *p, *q;

p=&i;

q=&j;

if(i>=95)

return(q);

else

return(p);

}

a. 11

b. 29

c. Compilation error

d. Runtime error

e. None of the above.

Ans. e. None of the above. the statement c = check(11,29) is assigning an int ptr to an int, so c has an address of an int (which has gone out of scope, since the function returns the address of a variable which had its scope only inside the function, since the parameters were passed by value) so the value printed can be anything. Instead, if the statement was c = *(check(11,29)) then c would have the value stored at the address returned by the function, which would most probably be 11, but it cannot be guaranteed since the variable i has fallen out of scope.

18. What shall be the output of the following code?

void main()

{int a[3][2]={ 1,2,

5,7,

6,8};

printf("\n%d",((a+1)-(&a+1)));

}

a. 0

b. -16

c. -2

d. -8

e. None of the above.

Ans. -2. I haven't been able to figure this one out. a is the address of the 2-d array, here a, &a, *a all give the same value, i.e., address of the array. (a+1) gives the address of the second row, it is the same as a[1]. *(a+1) gives the address of the first cell of the second row. **(a+1) gives the value of the element stored in the first cell in the second row. (*(a+1)+1) gives the address of the second cell of the second row. *(*(a+1)+1) gives the value of the element stored in the second cell in the second row.

19.What shall be the output of the following code?

main()

{

char str1[]="Hello";

char str2[]="Hello";

if(str1= =str2&& (*(str1+6)= =*(str2+6)))

printf("\n Equal");

else

printf("\n unequal");

}

a. Equal

b. Unequal

c. Compilation error.

d. Runtime error.

e. None of the above.

Ans. b. Unequal, because the addresses of the two strings are str1 and str2 and they are different.

20. Given that sizeof(int) is 2 , what is the output of the following code

main()

{

int a, b=255,c=127;

a=~b;

c=c^(~a & b|0);\

c=c^(~(~b));

printf("%d\n",c);

}

a. Error because of overflow;

b. 255

c. -256

d. 127

e. None of the above

Ans. d. 127

A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 % gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain, he would lose Rs. 10 in the bargain. The amount paid by him was Rs.- _______ for the horse and Rs.________ for the cart.

Ans :Cost price of horse: Rs. 400 &

Cost price of cart: Rs. 200

Explanation:

Let x be the cost of horse & y be the cost of the cart.

10 % of loss in selling horse = 20 % of gain in selling the cart

Therefore (10 / 100) * x = (20 * 100) * y

x = 2y ———–(1)

5 % of loss in selling the horse is 10 more than the 5 % gain in selling the

cart.

Therefore (5 / 100) * x - 10 = (5 / 100) * y

5x - 1000 = 5y

Substituting (1)

10y - 1000 = 5y

5y = 1000

y = 200

x = 400 from (1).

It takes Mr. Karthik y hours to complete typing a manuscript. After 2 hours, he was called away. What fractional part of the assignment was left incomplete?

Ans :(y - 2) / y.

Explanation:

To type a manuscript karthik took y hours.

Therefore his speed in typing = 1/y.

He was called away after 2 hours of typing.

Therefore the work completed = 1/y * 2.

Therefore the remaining work to be completed = 1 - 2/y.

(i.e.) work to be completed = (y-2)/y.

Five farmers have 7, 9, 11, 13 & 14 apple trees, respectively in their orchards. Last year, each of them discovered that every tree in their own orchard bore exactly the same number of apples. Further, if the third farmer gives one apple to the first, and the fifth gives three to each of the second and the fourth, they would all have exactly the same number of apples. What were the yields per tree in the orchards of the third and fourth farmers?

Ans :11 & 9 apples per tree.

Explanation:

Let a, b, c, d & e be the total number of apples bored per year in A, B, C, D &

E 's orchard. Given that a + 1 = b + 3 = c - 1 = d + 3 = e - 6

But the question is to find the number of apples bored per tree in C and D 's orchard.

If is enough to consider c - 1 = d + 3.

Since the number of trees in C's orchard is 11 and that of D's orchard is 13.

Let x and y be the number of apples bored per tree in C & d 's orchard respectively.

Therefore 11 x - 1 = 13 y + 3

By trial and error method, we get the value for x and y as 11 and 9.

A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 % gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain, he would lose Rs. 10 in the bargain. The amount paid by him was Rs.- _______ for the horse and Rs.________ for the cart.

Ans :Cost price of horse = Rs. 400 & the cost price of cart = 200.

Explanation:-

Let x be the cost price of the horse and y be the cost price of the cart.

In the first sale there is no loss or profit. (i.e.) The loss obtained is equal to the gain.

Therefore (10/100) * x = (20/100) * y

X = 2 * y —————–(1)

In the second sale, he lost Rs. 10. (i.e.) The loss is greater than the profit by Rs. 10.

Therefore (5 / 100) * x = (5 / 100) * y + 10 ——-(2)

Substituting (1) in (2) we get

(10 / 100) * y = (5 / 100) * y + 10

(5 / 100) * y = 10

y = 200

From (1) 2 * 200 = x = 400.

A contractor agreeing to finish a work in 150 days, employed 75 men each working 8 hours daily. After 90 days, only 2/7 of the work was completed. Increasing the number of men by ________ each working now for 10 hours daily, the work can be completed in time.

Ans :150 men.

Explanation:

One day's work = 2 / (7 * 90)

One hour's work = 2 / (7 * 90 *

One man's work = 2 / (7 * 90 * 8 * 75)

The remaining work (5/7) has to be completed within 60 days, because the

total number of days allotted for the project is 150 days.

So we get the equation

(2 * 10 * x * 60) / (7 * 90 * 8 * 75) = 5/7 where x is the number of men

working after the 90th day.

We get x = 225

Since we have 75 men already, it is enough to add only 150 men..

A man was engaged on a job for 30 days on the condition that he would get a wage of Rs. 10 for the day he works, but he have to pay a fine of Rs. 2 for each day of his absence. If he gets Rs. 216 at the end, he was absent for work for … days.

Ans :7 days

Explanation:

The equation portraying the given problem is:

10 * x - 2 * (30 - x) = 216 where x is the number of working days.

Solving this we get x = 23

Number of days he was absent was 7 (30-23) days..

Ans :30 days.

Explanation:

Before:

One day work = 1 / 20

One man's one day work = 1 / ( 20 * 75)

Now:

No. Of workers = 50

One day work = 50 * 1 / ( 20 * 75)

The total no. of days required to complete the work = (75 * 20) / 50 = 30

General Gasslefield, accused of high treason, is sentenced to death by the court-martial. He is allowed to make a final statement, after which he will be shot if the statement is false or will be hung if the statement is true. Gasslefield makes his final statement and is released. What could he have said?

General Gasslefield said: "I will be shot." If this statement was true, he would have been hung and thus not be shot. But then his statement would be false, which implies that he should be shot, making the statement true again, etc… In other words: the verdict of the court-martial could not be executed and the general was released..

A long, long time ago, two Egyptian camel drivers were fighting for the hand of the daughter of the sheik of Abbudzjabbu. The sheik, who liked neither of these men to become the future husband of his daughter, came up with a clever plan: a race would determine who of the two men would be allowed to marry his daughter. And so the sheik organized a camel race. Both camel drivers had to travel from Cairo to Abbudzjabbu, and the one whose camel would arrive last in Abbudzjabbu, would be allowed to marry the sheik's daughter. The two camel drivers, realizing that this could become a rather lengthy expedition, finally decided to consult the Wise Man of their village. Arrived there, they explained him the situation, upon which the Wise Man raised his cane and spoke four wise words. Relieved, the two camel drivers left his tent: they were ready for the contest! Which 4 wise words did the Wise Man speak?

Take each other's camel..

A boy leaves home in the morning to go to school. At the moment he leaves the house he looks at the clock in the mirror. The clock has no number indication and for this reason the boy makes a mistake in interpreting the time (mirror-image). Just assuming the clock must be out of order, the boy cycles to school, where he arrives after twenty minutes. At that moment the clock at school shows a time that is two and a half hours later than the time that the boy saw on the clock at home. At what time did he reach school?

The difference between the real time and the time of the mirror image is two hours and ten minutes (two and a half hours, minus the twenty minutes of cycling). Therefore, the original time on the clock at home that morning could only have been five minutes past seven: The difference between these clocks is exactly 2 hours and ten minutes (note that also five minutes past one can be mirrored in a similar way, but this is not in the morning!).Conclusion: The boy reaches school at five minutes past seven plus twenty minutes of cycling, which is twenty-five minutes past seven!.

In front of you are 10 bags, filled with marbles. The number of marbles in each bag differs, but all bags contain ten marbles or more. Nine of the ten bags only contain marbles of 10 grams each. One bag only contains marbles of 9 grams. In addition, you have a balance which can weigh in grams accurate, and you are allowed to use it only once (i.e. weigh a single time). How can you find out in one weighing, which bag contains the marbles of 9 grams?

Number the ten bags from 1 up to and including 10. Then take one marble from bag 1, two marbles from bag 2, three marbles from bag 3, etc. Place all 55 marbles that you selected from the bags together on the balance. The number of grams that the total weight of these 55 marbles differs from 550 grams, is equal to the number of marbles of 9 grams that are among those 55 marbles, and that is equal to the number of the bag which contains the marbles of 9 grams.

An old farmer died and left 17 cows to his three sons. In his will, the farmer stated that his oldest son should get 1/2, his middle son should get 1/3, and his youngest son should get 1/9 of all the cows. The sons, who did not want to end up with half cows, sat for days trying to figure out how many cows each of them should get. One day, their neighbour came by to see how they were doing after their father's death. The three sons told him their problem. After thinking for a while, the neighbour said: "I'll be right back!" He went away, and when he came back, the three sons could divide the cows according to their father's will, and in such a way that each of them got a whole number of cows. What was the neighbour's solution?

The neighbour borrowed an extra cow, to make the total number of cows 18. Then the oldest son got 1/2 of 18 is 9 cows, the middle son got 1/3 of 18 is 6 cows, and the youngest son got 1/9 of 18 is 2 cows. Since 9+6+2 = 17, the cows could be divided among the three brothers in such a way that the borrowed cow was left over, and could be returned to its owner..

It's always 1 to 6, it's always 15 to 20, it's always 5, but it's never 21, unless it's flying. What is this?

The answer is: a dice. An explanation:

"It's always 1 to 6″: the numbers on the faces of the dice,

"it's always 15 to 20″: the sum of the exposed faces when the dice comes to rest after being thrown,

"it's always 5″: the number of exposed faces when the dice is at rest,

"but it's never 21″: the sum of the exposed faces is never 21 when the dice is at rest,

"unless it's flying": the sum of all exposed faces when the dice is flying is 21 (1 + 2 + 3 + 4 + 5 + 6)..

A man has a wolf, a goat, and a cabbage. He must cross a river with the two animals and the cabbage. There is a small rowing-boat, in which he can take only one thing with him at a time. If, however, the wolf and the goat are left alone, the wolf will eat the goat. If the goat and the cabbage are left alone, the goat will eat the cabbage. How can the man get across the river with the two animals and the cabbage?

There are two solutions:

First, the man takes the goat across, leaving the wolf with the cabbage. Then he goes back. Next, he takes the wolf across. Then the man goes back, taking the goat with him. After this, he takes the cabbage across. Then he goes back again, leaving the wolf with the cabbage. Finally, he takes the goat across.
