9 : 36 :: 12 : ? :: 18 : 126
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 60.
9 : 36 ⇒ 9 × (9 ÷ 3 + 1) = 9 × (3 + 1) = 9 × 4 = 36
18 : 126 ⇒ 18 × (18 ÷ 3 + 1) = 18 × (6 + 1) = 18 × 7 = 126
Similarly;
12 : ? ⇒ 12 × (12 ÷ 3 + 1) = 12 × (4 + 1) = 12 × 5 = 60
Hence, the correct answer 60.
