Select the set in which the numbers are related in the same way as the numbers of the following set.
(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)
(23, 308, 15) (18, 187, 12)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. (14, 104, 9).
The logic used here is:
(23, 308, 15)
23 × (15 - 1) = 23 × 14 = 322
322 - 14 = 308
(18, 187, 12)
18 × (12 - 1) = 18 × 11 = 198
198 - 11 = 187
Similarly;
(14, 104, 9)
14 × (9 - 1) = 14 × 8 = 112
112 - 8 = 104
Hence, (14, 104, 9) is the correct answer.
