Answer:

A. 30

Read Explanation:

The answer is 30.

This is based on the logic of n3+nn^3 + n.

The Logic:

In the first pair (2:112 : 11):

  • 23+3=8+3=112^3 + 3 = 8 + 3 = 11 (Cubing the number and adding 3)

Applying a consistent pattern for the second pair (3:?3 : ?):

  • 33+3=27+3=303^3 + 3 = 27 + 3 = \mathbf{30}
