Back to paper

Identify the pattern and choose the correct option for the question mark
If 6 @ 3 = 21,
5 @ 2 = 12,
then 8 @ 4 = ?

Show answer & explanation

Correct answer: A

Explanation

6 @ 3 = 21

5 @ 2 = 12

6 @ 3 = (6 × 3) + 3 = 18 + 3 = 21

5 @ 2 = (5 × 2) + 2 = 10 + 2 = 12

That is,

a @ b = ab + b = b(a + 1)

Now,

8 @ 4 = (8 × 4) + 4 = 32 + 4 = 36

Correct answer: 36
