Correct Answer: 504
Solution :
Add one to the first and second numbers and then multiply the resultants to get the third number –
Row I:
(11 + 1) × (14 + 1) = 12 × 15 = 180
Row II:
(17 + 1) × (18 + 1) = 18 × 19 = 342
Similarly, in
Row III:
(23 + 1) × (20 + 1) = 24 × 21 = 504
So, the missing number is 504. Hence, the second option is correct.
