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.
Find the sum of two rows
10 2 3
13 8 9

Options

A. 78
B. 107
C. 123
D. None of these

Answer

D

Explanation

Direction (34-38):
For row-1:
An even number is followed by another even number = 10/2=5
An odd number is followed by another odd number (but not a perfect square) = 5 + 3 = 8
For row-2:
An odd number is followed by an even number (but not a perfect square) = 13x8 = 104
An even number is followed by an odd number
= 104 + 9 = 113
The sum is= 113+8=121
