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.)
(25, 8, 11)
(28, 8, 12)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (17, 7, 8).
Logic: (1st number + 2nd number) ÷ 3 = 3rd number.
(25, 8, 11) → (25 + 8) ÷ 3 = 33 ÷ 3 = 11
(28, 8, 12) → (28 + 8) ÷ 3 = 36 ÷ 3 = 12.
Similarly, (17, 7, 8) → (17 + 7) ÷ 3 = 24 ÷ 3 = 8
