Question
Select the set in which the numbers are NOT 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 - operation 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) (11, 25, 16) Â (24, 144, 36)ÂSolution
The logic followed here is as follows: (3rd number - 1st number)² = 2nd number (11, 25, 16)  = (16 - 11)² = 5² = 25 (24, 144, 36) = (36 - 24)² = 12² = 144 (16, 64, 24)  = (24 - 16)² = 8² = 64 (19, 225, 34) = (34 - 19)² = 15² = 225 (21, 361, 40)  = (40 - 21)² = 19² = 361 (6, 64, 15) = (15 - 6)² = 9² = 81
