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 1and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(31, 4, 47)
(17, 8, 81)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (19, 5, 44).
(31, 4, 47) → 31 + 42 = 31 + 16 = 47
(17, 8, 81) → 17 + 82 = 17 + 64 = 81
Similarly, (19, 5, 44) → 19 + 52 = 19 + 25 = 44
