Select the set in which the numbers are related in the same way as 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 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)
(8, 280, 5) (11, 308, 4)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (13, 637, 7).
The logic used here is:
(8, 280, 5)
280 ÷ 8 = 35
35 ÷ 7 = 5
(11, 308, 4)
308 ÷ 11 = 28
28 ÷ 7 = 4
Similarly,
(13, 637, 7)
637 ÷ 13 = 49
49 ÷ 7 = 7
Hence, (13, 637, 7) is the correct answer.
