Question

Find the odd thing from the following:

• A. 121
• B. 144
• C. 169
• D. 226

Hint:

To identify the odd one out, look for a pattern or common property among the items, such as being a perfect square, prime number, or multiple of a specific number.

Answer 1

The Correct Option is D

Let’s analyze the given numbers:
- 121 = \( 11^2 \) (perfect square)
- 144 = \( 12^2 \) (perfect square)
- 169 = \( 13^2 \) (perfect square)
- 226 is not a perfect square.
The first three numbers are perfect squares, but 226 is not. Therefore, 226 is the odd one out.
Thus, the correct answer is \( \boxed{4} \).
