Question : Directions: If 72 A 7 B 9 = 16, and 52 A 5 B 7 = 12, then 92 A 3 B 8 = ?
Option 1: 17
Option 2: 92
Option 3: 86
Option 4: 35
Correct Answer: 35
Solution : Given: 7 2 A 7 B 9 = 16; 5 2 A 5 B 7 = 12
7 2 A 7 B 9 = 16 = ((7) 2 ÷ 7) + 9 = (49 ÷ 7) + 9 = 7 + 9 = 16 5 2 A 5 B 7 = 12 = ((5) 2 ÷ 5) + 7 = (25 ÷ 5) + 7 = 5 + 7 = 12 Similarly, for 9 2 A 3 B 8 – = ((9) 2 ÷ 3) + 8 = (81 ÷ 3) + 8 = 27 + 8 = 35
Hence, the fourth option is correct.
