Question

Select the set in which the numbers are related in the same way as are 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 to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

(25, 625, 20)

Correct option is B

Information Given:
(16, 256, 16)
(9, 81, 9)

Logic:
Second number = (First number)² and Third number = √(Second number)

Explanation:
(16, 256, 16)
16² = 256 ✔
√256 = 16 ✔

(9, 81, 9)
9² = 81 ✔
√81 = 9 ✔

Check options:
A: 4² = 16 ✔, √16 = 4 ≠ 6 ✘
B: 8² = 64 ✔, √64 = 8 ✔
C: 12² = 144 ✔, √144 = 12 ≠ 10 ✘
D: 25² = 625 ✔, √625 = 25 ≠ 20 ✘

Final Answer:
(8, 64, 8)

Final Correct Option:
B
