There are two rows given and to find out the resultant of a particular row we need to follow the following steps: -
STEP 1: If an even number is followed by an odd number then the resultant will be the addition of both the numbers.
STEP 2: If an odd number is followed by a perfect square then the resultant will be the difference of that square number and the odd number.
STEP 3: If an odd number is followed by another odd number (but not a perfect square) then the resultant will be the addition of both the numbers.
STEP 4: If an odd number is followed by an even-number (but not a perfect square) then the resultant comes by multiplying the numbers.
STEP 5: If an even number is followed by another even number then the resultant will be the division of first number by the second number.
If the sum of the resultants of two rows is 52. Then Lfind the value of x.
11 4 9
30 6 X

Options

A. 16
B. 27
C. 10
D. 15

Answer

C

Explanation

For row -1:
An odd number is followed by a perfect square
= 11-4 = 7
An odd number is followed by a perfect square
= 9-7 = 2
For row-2:
An even number is followed by another even number = 30/6 = 5
The resultant of row-2 is = 52-2 = 50
Then value of X must be = 10
