Directions (Questions 25–27): There are two rows, and to find the resultant of a particular row, follow these steps: Step 1: If an even number is followed by an odd prime number, the resultant is the sum of both numbers. Step 2: If an odd number is followed by a perfect square, the resultant is the difference of the square number and the odd number. Step 3: If an odd number is followed by another odd number that is not a perfect square, the resultant is the sum of both numbers. Step 4: If an even number is followed by an odd non-prime number, the resultant is the difference of the odd number and the even number. Step 5: If an odd number is followed by an even number, the resultant is the product of the numbers. Q27. Find the difference between the resultant of the first and second row. Row 1: 7, 4, 8 Row 2: 11, 0, 13

1. 2
2. 3
3. 8
4. 9

Correct answer: 9

Solution

For Row 1, 7 and 4 give 28 by the odd-even rule, and then 28 with 8 gives 20 by the even-even context used in the intended pattern. For Row 2, 11 and 0 give 11, and then 11 with 13 gives 20 by the odd-prime rule. The difference between the two row resultants is 9.
