19. Potatoes are made up of 99% water and 1% “potato matter.” Jack bought 100 pounds of
potatoes and left them outside in the sun for a while. When he returned, he discovered that the potatoes had dehydrated and were now only made up of 98% water. How much did the potatoes now weigh?
Ans: 50 pounds.
Assuming the percentages are by weight - ie, 99% of the weight of a potato is water. 
Now - initial amount of water = (99%) * 100 lbs = 99 lbs. 

Let the weight evaporated be = x lbs. 
So, new weight = 100 - x lbs, out of which 98% is water. 
So, new amount of water = (98%) * (100 - x lbs) = ( 98 - 0.98x )lbs 

Difference between them is x (since it is the weight evaporated) 

So, 99 - (98 - 0.98x) = x 
=> 1 = 0.02x 
=> x = 1/0.02 
=> x = 50 

So, weight lost = 50lbs 
weight of potatoes now = 100-50 = 50lbs
