Select the option in which the numbers shares the same relationship in set as that shared by the numbers in the given set. (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)
(8, 63, 81)
(11, 120, 144)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (9, 80, 100).
(8, 63, 81) → (8 - 1) × √81 = 7 × 9 = 63
(11, 120, 144) → (11 - 1) × √144 = 10 × 12 = 120
Similarly, (9, 80, 100) → (9 - 1) × √100 = 8 × 10 = 80
