Today we look at a few questions that appeared in XAT 2014 exam. Note that XAT 2014 questions are also a good set of practice questions for CAT 2014.

The questions below have the question followed by a Video Solution!

1.Evaluate the following:

The solution to this problem is explained in the Video below:

2. Two numbers, 297

_{B}and 792

_{B}, belong to base B number system. If the first number is a factor of the second number then the value of B is

11

12

15

17

19

3. Aditya has a total of 18 red and blue marbles in two bags (each bag has marbles of both colors). A marble is randomly drawn from the first bag followed by another randomly drawn from the second bag, the probability of both being red is 5/16. What is the probability of both marbles being blue?

4. The probability that a randomly chosen positive divisor of 10

^{29}is an integer multiple of 10

^{23}is a

^{2}/b

^{2}, then 'b - a' would be:

8

15

21

23

45

5. The number of the possible values of X in the equation |X + 7| + |X - 8| = 16 is

0

1

2

3

4

6. A polynomial ax

^{3}+ bx

^{2}+ cx + d intersects x-axis at 1 and -1, and y-axis at 2. The value of b is:

-2

0

1

2

Cannot be Determined

7. S = ax/(b+c+x) where all parameters are positive. If x is increased and all other terms are kept constant, S will

Increase

Decrease

Increases and then decreases

Decreases and then increases

Cannot be determined

8. x, 17, 3x - y

^{2}- 2, and 3x + y

^{2}- 30, are four consecutive terms of an increasing arithmetic sequence. The sum of the four number is divisible by:

2

3

5

7

11

In our future posts, we will be adding more questions from XAT 2014, which should be also be a very good practice set for CAT 2014.
