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 a two-digit odd number is followed by a prime number, the first number is to be multiplied by the prime number. (ii) If an even number is followed by another even number, the first number is to be divided by the second number. (iii) If an odd number is followed by a composite odd number, the first number is to be added to the second number. (iv) If an even number which is a multiple of 5 is followed by another number which is also a multiple of 5, the second number is to be subtracted from the first number. (v) If a number which is a perfect square is followed by another number which is also a perfect square, the square roots of the two numbers is to be multiplied.
