Question
Select the option in which the numbers are related in
the same way as are the numbers of the following sets. (11, 13, 72) (19, 12, 93) (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13-Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)Solution
The logic followed here is: (1st number + 2nd number) x 3 = 3rd number. (11, 13, 72) → (11 + 13) x 3 = 72 → 24 x 3 = 72 → 72 = 72 (19, 12, 93) → (19 + 12) x 3 = 93 → 31 x 3 = 93 → 93 = 93 Now, checking the options: Option (B): (15, 23, 114) (15 + 23) x 3 = 114 38 x 3 = 114 114 = 114 Hence, the correct answer is (B).
