Select the set in which the numbers are related in the same way as are the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent 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)
(14, 231, 19) (7, 154, 15)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e.(13, 210, 17).
The logic used here is:
(14, 231, 19)
(14 + 19) × 7 = 33 × 7 = 231
(7, 154, 15)
(7 + 15) × 7 = 22 × 7 = 154
Similarly,
(13, 210, 17)
(13 + 17) × 7 = 30 × 7 = 210
Hence, (13, 210, 17) is the correct answer.
