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 another odd number which is a perfect square then they are to be added.
(ii) If an even number is followed by an odd number or an odd number is followed by an even number, they are to be multiplied.
(iii) If an even number is followed by another even number, the first number is to be divided by the second number.
(iv) If an even number which is a multiple of 5 is followed by an odd number which is also a multiple of 5, then the second number is to be subtracted from the first number.

248 8 25
3 $\times$ 28
If x is the resultant of the first row, what is the resultant of the second row?

• A. 12
• B. 6
• C. 18
• D. 16
• E. None of these

Answer 1

The correct option is B 6

$\frac{248}{8}=31$ [Condition (iii)]
31 + 25 = 56 [Condition (i)]
Now, $3\times 56=168$ [Condition (ii)]
$\frac{168}{28}=6$ [Condition (iii)]
