Answer 2

The odd number among the given options is 512. (option A)

Given,

Four numbers in options:

512, 841, 576, 289.

To find,

Odd one out.

Solution,

It can be seen that the four numbers given here, are

512, 841, 576, 289.

We have to find the odd one out. To determine the odd one, observe the given numbers.

Here, the given numbers are such that,

512 = (8)³

841 = (29)²

576 = (24)²

289 = (17)².

We can see from above, that all other numbers except 512 are squares of the numbers, while 512 is the cube of a number (8).

⇒ the odd one among four numbers = 512.

Therefore, the odd number among the given options is 512. (option A)
