Question
Select the option that is related to the fifth number in
the same way as the second number is related to the first number and the fourth number is related to the third number. 12 : 42 :: 31 : 99 :: 24 : ?Solution
Logic: (1st number x 3) + 6 = 2nd number. For, 12 : 42 → (12 x 3) + 6 → 36 + 6 = 42 For, 31 : 12 → (31 x 3) + 6 → 93 + 6 = 99 Similarly, for 24 : ? (24 x 3) + 6 72 + 6 = 78 Hence, the correct answer is. (B).
