Select the set in which the numbers are related in the same way as are 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 to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(20, 76, 91)
(87, 41, 123)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (84, 47, 126).
(20, 76, 91) → (91 - 20) + 5 = 71 + 5 = 76
(87, 41, 123) → (123 - 87) + 5 = 36 + 5 = 41
Similarly, (84, 47, 126) → (126 - 84) + 5 = 42 + 5 = 47
