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.
