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)
(2, 9, 85) (3, 9, 90)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. (7, 9, 130).
The logic used here is:
(2, 9, 85)
22 = 4
92 = 81
4 + 81 = 85
(3, 9, 90)
32 = 9
92 = 81
9 + 81 = 90
Similarly,
(7, 9, 130)
72 = 49
92 = 81
49 + 81 = 130
Hence, (7, 9, 130) is the correct answer.
