Question
Select the set in which the numbers are NOT related in
the same way as are the numbers of the following set. (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, 46, 138) (45, 90, 270)Solution
The first number is multiplied by 2 to get the second number and the second number is multiplied by 3 to get the third number. (23, 46, 138) → (23 X 2) = 46, (46 X 3) = 138 (45, 90, 180) → (45 X 2) = 90, (90 X 3) = 270 (38, 76, 224) → (38 X 2) = 76, (76 X 3) = 228 (27, 54, 162) → (27 X 2) = 54, (54 X 3) = 162 (49, 98, 294) → (49 X 2) = 98, (98 X 3) = 294 (52, 104, 312) → (52 X 2) = 104, (104 X 3) = 312
