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.)
(166, 13, 4) (2113, 46, 7)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (481, 22, 5).
The logic used here is:
(166, 13, 4)
132 = 169
169 - 3 = 163
42 = 16
16 - 3 = 13
(2113, 46, 7)
462 = 2116
2116 - 3 = 2113
72 = 49
49 - 3 = 46
Similarly,
(481, 22, 5)
222 = 484
484 - 3 = 481
52 = 25
25 - 3 = 22
Hence, option 2 is the correct answer.
