Select the set in which the numbers are related in the same way as 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).
(16, 7, 37) (28, 9, 55)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (13, 4, 25).
(16, 7, 37) = 16 + 7 + (7 × 2) = 16 + 7 + 14 = 37
(28, 9, 55) = 28 + 9 + (9 × 2) = 28 + 9 + 18 = 55
Similarly, (13, 4, 25) = 13 + 4 + (4 × 2) = 13 + 4 + 8 = 25
