Select the set in which the numbers are related in the same way as are the numbers of the given 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.)
(29, 77)
(24, 62)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (19, 47).
(29, 77) → (29 × 3) - 10 = 87 - 10 = 77
(24, 62) → (24 × 3) - 10 = 72 - 10 = 62
Similarly, (19, 47) → (19 × 3) - 10 = 57 - 10 = 47
