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

If x is the resultant of the first row, then what will be the resultant of the second row?

A5
B10
C45

if x is equal to 55 then as per rule no 5 we have to divide 55 by 11 and we get 5 as answer so as per rule no 1 we should multiply 5 by 15 giving us a result of 75
