Question

Select the related number from the given alternatives:
12 : 30 :: 20 : ?

• A. 48
• B. 32
• C. 35
• D. 42

Hint:

In number analogies, always check for patterns involving multiplication, addition, or subtraction.

Answer 1

The Correct Option is D

This is a number analogy problem. The pattern here involves multiplying the first number by 2.5: - \( 12 \times 2.5 = 30 \) - \( 20 \times 2.5 = 50 \), but we must subtract 8 to get the answer: \( 50 - 8 = 42 \).
Thus, the correct answer is (D) 42.
