Question

Comprehension

Direction: In each of the following questions two rows of numbers are given. The resultant number in each row is to be worked out separately based on the following rules and the question below the rows of numbers are to be answered. The operations of numbers progress from left to right.

Rules:

i) If an even number is followed by an odd prime number, then subtract even number from that odd prime number.

ii) If  an even number is followed by a perfect square, then divide even number by perfect square number.

iii) If an even number is followed by a composite number, then subtract the smaller one from the greater one.

iv) if odd number is followed by odd prime number, then subtract smaller one from the greater one.

v) If an odd number is followed by any composite number, subtract smaller one from the greater one.

Note: If any two conditions co-incite we will consider the first one obtained from (i to v) for the operations.

17    15    5

32    16    7

What would be multiplication of resultants of both the rows?

1. 10
2. 12
3. 15
4. 18
5. None of these

Answer 1

Correct Answer - Option 3 : 15

In row I: 17    15    5

17 is an odd number is followed by any composite number, subtract smaller one from the greater one.

17 - 15 = 2 

2 is an even number is followed by an odd prime number, then subtract even number from that odd prime number.

5 - 2 = 3

In row II: 32    16    7

32 is  even number is followed by a perfect square, then divide even number by perfect square number.

32 ÷ 16 = 2 

Now, 2 is an even number is followed by an odd prime number, then subtract even number from that odd prime number.

7 - 2 = 5

5 x 3 = 15

Hence, multiplication of resultants of both the rows would be 15.
