Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different.
(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: C
Explanation
The correct answer is option 3 i.e. 9 : 742.
Logic Used: (First Number)3 + 11 = Second Number
Except for Option 3 ⇒ 9 : 742
= (9)3 + 11 = 729 + 11 = 740
Thus, 9 : 742 is odd one out.
