Choose the different number:
- ((a))
38
- ((b))
39
- ((c))
40
- ((d))
36
Show Answer
36
The logic followed here is:
| 38 | Not a perfect square |
|---|---|
| 39 | Not a perfect square |
| 40 | Not a perfect square |
| 36 | A perfect square (62) |
The numbers 38, 39, and 40 are not perfect squares.
Whereas,
36 is a perfect square.
Hence, the correct answer is "Option 4".
Note: Based on the logic of odd and even numbers, the odd one is 39. However, the official answer key states that the correct answer is 'Option 4'.
Therefore, we will use the logic of a square number instead.
