Select the triad in which the numbers are related in the same way as are the numbers of the following triads.
14-15-145
12-27-195
(NOTE: Operations should be performed on the whole numbers, without breaking down the aumbers into its constitue digits. E.g. 13-Operations on 13 such as adding/subtracting/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)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 17-31-240.
Logic: The sum of the first two numbers × 5 = third number.
(14-15-145) → (14 + 15) × 5 = 29 × 5 = 145
(12-27-195) → (12 + 27) × 5 = 39 × 5 = 195
Similarly, 17 - 31 - 240 → (17 + 31) × 5 = 48 × 5 = 240
