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)
Answer & explanation
Correct answer: option 3
(23, 25, 16)
(21, 17, 256)
The logic followed here is :
(Ist number - second number)4 = Third number
As
(23 - 25)4 = 16
(21 - 17)4 = 256
Same as in (18, 15, 81)
(18 - 15)4 = 81
