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 /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)
(7, 52), (9, 84)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (13, 172).
Logic : ( First Number )2 + 3 = Second Number
⇒(7, 52)
= (7)2 + 3 = 49 + 3 = 52
⇒(9, 84)
= (9)2 + 3 = 81 + 3 = 84
Similarly ,Option 1 follows the same logic
(13, 172)
= (13)2 + 3 = 169 + 3 = 172
Hence, (13, 172) is the correct answer.
