## Comment on

Mean is Less Than 4## in gre if number type is not

Because i intuitively thought mean will be integer only, so kept 3 will be next possible mean. So my answer was C D E and F.

## Unless it is specifically

Unless it is specifically stated otherwise, a number can be any real number.

Of course, sometimes the nature of a real world question implies that a number may be an integer and/or positive.

For example, if a question says x = the length of a rectangle, we know that x > 0

Likewise, if a question tells us that x = the number of children at a party, we know that x is a positive integer.
