Identify the number that is different from the rest.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 252.
The logic used here is:
196, 256, and 121 are perfect squares.
196 = 142
256 = 162
121 = 112
Whereas, 252 is not a perfect square.
Hence, the correct answer is 252.
