Select the set in which the numbers are related in the same way as 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.)
(13, 18, 21) (11, 25, 8)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (14, 33, 9).
The logic used here is:
(13, 18, 21) = 18 + 21 = 39, 39 ÷ 3 = 13
(11, 25, 8) = 25 + 8 = 33, 33 ÷ 3 = 11
Similarly;
(14, 33, 9) = 33 + 9 = 42, 42 ÷ 3 = 14
