Logic Weighing Puzzle

You have 100 killograms of puzzling mangoes, which are 99 percent water by weight.
You let them dehydrate until they are 98 percent water.

How much do they weigh now ?

For Answer

Solution: Perhaps surprisingly, the mangoes now weigh 50 kilograms. The sack of mangoes originally weighed 100 kilograms, and 1 percent of its weight, or 1 pound, was non-water. If that 1 pound now makes up 2 percent of the total weight, then the total weight must be 50 kilograms.
