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.)
(7, 65)
(11, 145)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (8, 82).
Logic: (1st number + 1)2 + 1 = 2nd number
(7, 65) ⇒ 7 + 1 = (8)2 + 1 =65
(11, 145) ⇒11 +1 = (12)2 + 1 = 145
Similarly, (8, 82) ⇒ 8 + 1 = (9)2 + 1 = 82
