Correct Answer: 42


Solution : Given:
12 : 20 :: 30 : ?

The number in each pair is the sum of a natural number and its square.
Like, (12 : 20)→(3)2 + 3 = 9 + 3 = 12
(4)2 + 4 = 16 + 4 = 20
Similarly, follow the same pattern for (30 : ?)→(5)2 + 5 = 25 + 5 = 30
(6)2 + 6 = 36 + 6 = 42

So, 30 is related to 42. Hence, the third option is correct.
