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 added. (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 the 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 second one is to be subtracted from the first number.
