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.)
(7, 13, 10) (15, 21, 18)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (11, 15, 13).
The logic used here is:
(7, 13, 10)
7 + 13 = 20
20 ÷ 2 = 10
(15, 21, 18)
15 + 21 = 36
36 ÷ 2 = 18
Similarly,
(11, 15, 13)
11 + 15= 26
26 ÷ 2 = 13
Hence, option 3 is the correct answer.
