Direction: In every question, two rows are given and to find out the resultant of a particular row you need to follow the following rules:
Rule 1: If an even number is followed by an odd number, then they are to be added.
Rule 2: If an odd number is followed by a perfect square, then they are to be added.
Rule 3: If an odd number is followed by a prime odd number, then the first number is to be divided by the second number.
Rule 4: If an even number is followed by an even number the small number is to be subtracted from the large number.
Rule 5: If an odd number is followed by an even number (not a perfect square), then they are to be multiplied.
Row- I, 6 15 7 9
Row- II, 11 8 X 3
If X is the resultant of row I, then what would be the difference between the resultant of row I and row II?
