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 its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/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.)
(10, 20, 4)
(15, 30, 6)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (20, 40, 8).
Logic: (10, 20, 4)
2 2 = 4, 2 5 = 10, 2 10 = 20
(15, 30, 6)
3 2 = 6, 3 5 = 15, 3 10 = 30
Similarly, (20, 40, 8)
4 2 = 8, 4 5 = 20, 4 10 = 40
Hence the correct answer is (20, 40, 8).
