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 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)
(9. 343. 2)
(12, 729, 3)
Answer & explanation
Correct answer: option 4
(9. 343. 2)
(12, 729, 3)
Logic followed here is :
(Ist number - Third number )3 = second number
(9 -2 )3 = 73 = 343
Same as
(9 -2 )3 = 73 = 343
similarly in option 3
(12 -7 )3 = 53 = 125
