Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?
(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 t and 3 and then performing mathematical operations on 1 and 3 is not allowed)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1. i.e. 16 - 276.
Logic followed : (First Number )2 = Second Number
Option 1 : 16 - 276
(16)2 = 256
So , it is the odd one out as it does not follow the same logic.
Hence, 16 - 276 is the correct answer.
