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 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6 - 48.
Logic Used: (First Number)2 + First Number = Second Number
Except for Option 4,
⇒ 6 - 48 = (6)2 + 6 = 36 + 6 = 42
Thus, 6 - 48 is odd one out.
