Question

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 of
numbers is to be answered. The operations on numbers
progress from left to right.
Rules:
(i) If an odd number is followed by another composite odd number, then they are to be multiplied.
(ii) If an even number is followed by an odd number,
then they are to be added.
(iii) If an even number is followed by a number which
is a perfect square, then the even number is to be subtracted from the perfect square.
(iv) If an odd number is followed by a prime odd
number, then the first number is to be divided by the second number.
(v) If an odd number is followed by an even number, then the even number is to be subtracted from the odd number.
15 3 65
4 81 12
Find the number obtained on dividing the resultant of the first row by the resultant of the second row.
A. 9
B. 5
C. 10
D. 14​

Answer 1

Answer option b) 5 because in first row the resultant is 325 and in second row we get 65 so 325/65 =5

Solution: In First Row between 15 and 3 rule no 4 would apply and we get 5 then between 5 and 65 rule i would apply then we get 325.

In the second row between 4 and 81 rule no 3 would apply and we would get 77 .then between 77 and 12 rule no 5 will apply so we get 65

(ALL OF THIS IN LEFT TO RIGHT ORDER)
