A salesman buy 200 kgs of fresh cucumbers from farm containing 99% water. When he reached his godown, the cucumbers contained 98% water due to hot weather.
What is the weight of cucumbers in kgs now?
If the cucumbers reduced 1% more water at the end of the day then how much more weight in kgs reduced?
Hint, a surprising result achieved when cucumbers dried out.

The variation in difficulty makes you think twice but I’m happy 
With this one the dry wt is constant and is 2kg
And the start water content is 198kg
After the hot day the 2kg (constant) is now 2% which makes the total wt = 2 * 100 / 2 = 100kg and water content 98kg
Further 1% water loss is 98 * 1 /100 = .98 kg. Total weight now is 99.02 kg
