In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. 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 its constituent digits. E.g. 13-Operations on 13 such as adding subtracting multiplying ete. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on and 3 is not allowed.)
(7,336)
(9,722)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (4, 57).
(7, 336) → 73 - 7 = 336
(9, 722) → 93 - 7 = 722
Similarly, (4, 57) → 43 - 7 = 57
