Select the set in which the numbers are related in the same way as are the numbers of the given sets.
(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.)
(23, 25, 16)
(21, 17, 256)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. (18, 15, 81)
Given sets:
(23, 25, 16)
Here, (23 - 25)4 = 24 = 16
Similarly, (21, 17, 256)
= (21 - 17)4 = 44 = 256
Let us check all the options:
1. (14, 19, 125)
= (14 - 19)4 = 54 = 625 ≠ 125
2. (27, 23, 64)
(27 - 23)4 = 44 = 256 ≠ 64
3. (18, 15, 81)
= (18 - 15)4 = 34 = 81 = 81
4. (11, 9, 12)
(11 - 9)4 = 24 = 16 ≠ 12
Hence, (18, 15, 81) is the correct answer.
