Correct Answer: 720

Solution : In a row of the given table, find the square of the sum of the first and second numbers and the square of the difference between the first and second numbers and then subtract both the resultant numbers to obtain the third number.

In the first row→(8 + 7) ² – (8 – 7) ² = (15) ² – (1) ² = 225 – 1 = 224
In the second row→(11 + 13) ² – (11 – 13) ² = (24) ² – (–2) ² = 576 – 4 = 572
Similarly, in the third row→
(12 + 15) ² – (12 – 15) ² = (27) ² – (–3) ² ​ = 729 – 9 = 720

So, 720 is the missing number in the given figure. Hence, the second option is correct.
