Select the set in which the numbers are related in the same way as the numbers of the given 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.)
(15, 23, 31)
(33, 41, 49)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (20, 28, 36).
Logic: 1st number + 8 = 2nd number, 2nd number + 8 = 3rd number.
(15, 23, 31) ⇒ 15 + 8 = 23, 23 + 8 = 31
(33, 41, 49) ⇒ 33 + 8 = 41, 41 + 8 = 49
Similarly, (20, 28, 36) ⇒ 20 + 8 = 28, 28 + 8 = 36
