A20

B18

C19

D17

Answer:

A. 20

Read Explanation:

Look for a pattern:

  • (9 @ 3 = 36)

  • (6 @ 2 = 16)

Notice:

9@3=(9+3)×3=12×3=369 @ 3 = (9+3)\times 3 = 12\times 3 = 36
6@2=(6+2)×2=8×2=166 @ 2 = (6+2)\times 2 = 8\times 2 = 16

Using the same rule:

8@2=(8+2)×2=10×2=208 @ 2 = (8+2)\times 2 = 10\times 2 = 20

Answer: 20
