Correct Answer: 17


Solution : Add two to both the first and the second numbers and multiply the resultants –
Row I: (7 + 2) × (14 + 2) = 9 × 16 = 144
Row II: (11 + 2) × (16 + 2) = 13 × 18 = 234
Similarly, in Row III: (12 + 2) × (X + 2) = 266
⇒ 14 × (X + 2) = 266
⇒ X + 2 = 266 ÷ 14 
⇒ X = 19 – 2
⇒ X = 17

So, the missing number is 17. Hence, the first option is correct.
