Select the set in which the numbers are related in the same way as are 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)
(6, 15, 1) (5, 6, 3)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (15, 21, 8).
The logic used here is:
(1st number - 3rd number) × 3 = = 2nd number
(6, 15, 1) = (6 - 1) × 3 = 15
(5, 6, 3) = (5 - 3) × 3 = 6
Similarly;
(15, 21, 8) = (15 - 8) × 3 = 21
