Correct Answer: 29
Solution :
Given:
169 is related to 11 and 625 is related to 23.
Subtract 2 from the square root of the first number to get the related number –
Like, 169 : 11→(√169) – 2 = 13 – 2 = 11
And, 625 : 23→(√625) – 2 = 25 – 2 = 23
Similarly, follow the same pattern for (961 : ?)→(√961) – 2 = 31 – 2 = 29
So, 961 is related to 29. Hence, the first option is correct.
