Select the set in which the numbers are related in the same way as are the numbers of the following set.
(66, 57, 48)
(94, 85, 76)
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/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.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (81, 72, 63).
Logic: (1st number + 3rd number) ÷ 2 = 2nd number
(66, 57, 48): (66 + 48) ÷ 2 = 114 ÷ 2 = 57
(94, 85, 76): (94 + 76) ÷ 2 = 170 ÷ 2 = 85
Similarly, (81, 72, 63) = (81 + 63) ÷ 2 = 144 ÷ 2 = 72
