If 40 * 30 # 20 @ 10 = 1230 and 70 * 6 # 10 @ 3 = 433, then 8 * 4 # 5 @ 9 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 46.
* means ×, # means +, @ means +
40 * 30 # 20 @ 10 = 1230 → (40 × 30) + 20 + 10 = 1230
70 * 6 # 10 @ 3 = 433 → (70 × 6) + 10 + 3 = 433
Then 8 * 4 # 5 @ 9 = ? → (8 × 4) + 5 + 9 = 46
