How to calculate the amount of dry sludge, moisture content, and amount of dewatered sludge?

How many tons of sludge will be dehydrated when the moisture content is reduced from 80% to 60%? In 10 tons of sludge, the content of dry sludge is: 10x (100% -80%)=2 tons, which is equivalent to 60% of the sludge. The proportion of water accounts for 60%, and the content of dry sludge accounts for ...
