Question

suppose an amount increase by 50%, then decrease by 50%. will the amount after the decrease be the same as the original amount

Answer 1

Lets say you have "100" apples.

If you lost 50% of those 100 apples, (50 apples) and then half of them went rotten, then no, it wouldn't be the same. But if you picked them all back up, and none of them were damaged, then yes, they would stay the original amount.
