Correct Answer: 9


Solution : Given:

23 ? 12
6 13 7
138 117 84

In each column multiply the first two numbers to obtain the third number.
Column 1: 23 × 6 = 138
Column 2: (?) × 13 = 117
⇒ (?) = 117 ÷ 13
⇒ (?) = 9
Column 3: 12 × 7 = 84

So, 9 is the missing number. Hence, the first option is correct.
