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/substracting/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, 15, 11)
(9, 19, 14)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (11, 23, 17).
Logic: (7, 15, 11)
(15 + 7) ÷ 2 = 22 ÷ 2 = 11
(9, 19, 14)
(19 + 9) ÷ 2 = 28 ÷2 = 14
Similarly, (11, 23, 17).
(23 + 11) ÷ 2 = 34 ÷ 2 = 17
