Question

Directions:- Study the following information carefully to answer the question given below.

Two rows of numbers are given in the question. The resultant number in each row has to be worked out separately based on the following rules. The operation of numbers progresses from left to right.

Rules:-
(i) If an odd number is followed by a two-digit even number then they are to be added.
(ii) If an odd number is followed by a two-digit odd number then the second number is to be subtracted from the first number.
(iii) If an even number is followed by a number which is a perfect square of a number then the second number is to be divided by the first number.
(iv) If an even number is followed by a two-digit even number then the first number is to be multiplied by the second number.

40 30 3600
15 24 17
What is the sum of the two resultant numbers of the set of numbers given above?

• A. 22
• B. 25
• C. 28
• D. 42
• E. None of these

Answer 1

The correct option is B 25

First Set of Numbers
40 30
$\Rightarrow 40\times 30=1200$ [Rule (iv)]
1200 3600
$\Rightarrow \frac{3600}{1200}=3$ [Rule (iii)]
Second Set of Numbers
15 24
$\Rightarrow 15+24=39$ [Rule (i)]
39 17
$\Rightarrow 39-17=22$ [Rule (ii)]
Now, $3+22=25$
