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 /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.)
(71, 114, 157)
(36, 79, 122)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (25, 68, 111).
(71, 114, 157): (71 + 157) ÷ 2 = 228 ÷ 2 = 114
(36, 79, 122): (36 + 122) ÷ 2 = 158 ÷ 2 = 79
Similarly, (25, 68, 111): (25 + 111) ÷ 2 = 136 ÷ 2 = 68
