Correct Answer: 400


Solution : Given:
7 : 36 :: 16 : 225 :: 21 : ?

Subtract 1 from the first number, and then square the resultant, to get the second number –
Like, 7 : 36→(7 – 1) 2 = 36
And, 16 : 225→(16 – 1) 2 = 225
Similarly, follow the same pattern for 21 : ?→(21 – 1) 2 = 400

So, 400 is the required missing term. Hence, the first option is correct.
