heinz produces tomato puree by boiling tomato juice . the tomato puree has only 20 % water while the tomato juice has 90 % water . how many liters of tomato puree will be obtained from 50 litres of tomato juice ?
"answer : explanation : in each of the solutions , there is a pure tomato component and some water . so while boiling , water evaporates but tomato not . so we equate tomato part in the both equations . â ‡ ’ â ‡ ’ 10 % ( 50 ) = 80 % ( x ) â ‡ ’ â ‡ ’ x = 6.25 liters . answer : d"
divide(multiply(divide(subtract(const_100, 90), const_100), 50), divide(subtract(const_100, 20), const_100))
