Cube of an odd number is odd.

In each of the following questions, two rows of numbers are given. The resultant number of each row is to be worked out separately based on the following rules and then answer the questions that follow. The operation of numbers progress from left to right. Rules - (i) If an odd number is followed by another odd number which is a perfect square, then they are to be added. (ii) If an even number is followed by an odd number or an odd number is followed by an even number, they are to be multiplied. (iii) If an even number is followed by another even number, the first number is to be divided by the second number. (iv) If an even number which is a multiple of 5 is followed by an odd number which is also a multiple of 5, then second number is to be subtracted from the first number. 7 9 9 72 8 25 What is the sum of the resultants of both rows?
