Really, really simple math

You have a sack of potatos which weighs 100 lbs. The potatos are 99% water. (Ignore the sack.) You leave the potatos out for a couple of days. The potatos are now 98% water. What does the sack of potatos weigh?

Or is it potatoes? As Dan Quayle said, "The future will be better tomorrow."

What? No takers? C'mon!

A 100 lb. sack of potatos that is 99% water gets dehydrated ( a bit) so that it is now 98% water. What does the sack of potatos now weigh?

Easy!

50 lbs.

Obviously no potatoes left the sack, so if it started with 1 lb. potatoes, it will still have 1 lb. potatoes. If x=weight of sack of potatoes, .02x=1lb. x=50lbs.
