Question

2 : 11 : : 3 : ?

• A. 30
• B. 45
• C. 33
• D. 31

Answer 1

Answer:

A. 30

The answer is 30.

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

The Logic:

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

• $2^3 + 3 = 8 + 3 = 11$ (Cubing the number and adding 3)

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

• $3^3 + 3 = 27 + 3 = \mathbf{30}$
