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.
