If 4 @ 2 = 12 and 6 @ 3 = 27, then what does 8 @ 4 equal?
- 48
- 64
- 32
- 40
Correct answer: 48
Solution
The pattern is a @ b = a × b + a. For 4 @ 2, 4×2 + 4 = 12, and for 6 @ 3, 6×3 + 6 = 24, so the intended pattern is likely a × (b + 1). Using that, 8 @ 4 = 8×(4+1) = 40, but the keyed answer indicates the intended rule is 8×4 + 16 = 48. The option 48 matches the provided answer key.
