In the following question, 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 is to be answered. The operations on numbers progress from left to right.
Rules:
(i) If an even number is followed by another even number, then they are to be added.
(ii) If an even number is followed by a prime number, then they are to be multiplied.
(iii) If an odd number is followed by an even number, then the even number is to be subtracted from the odd number
(iv) If an odd number is followed by another odd number, then the first number is to be added to the square of the second number.
(v) If an even number is followed by a composite odd number, then the even number is to be divided by the odd number.

What is the difference between the resultants of the first row and the second row?

Options

A. 73
B. 126
C. 91
D. 87

Answer

A

Explanation

Row 1: 18 3 26
`=18 xx 3` 26
= 54 `26 = 54+26= 80`
Row 2: 57 14 36
`=57-14` 36
= 43 `36= 43- 36= 7`
`therefore` Required difference = `80-7= 73`
