Heinz produces tomato puree by boiling tomato juice. The tomato puree has only 20% water while the tomato juice has 90% water. How many litres of tomato puree will be obtained from 20 litres of tomato juice?
A. 2 litres

B. 2.4 litres

C. 2.5 litres

D. 6 litres

• C 2.5 liters
  
  Tomato Juice has 90% water and 10% tomato
  Tomato puree has 20% water and 80% tomato
  So 20 liter of tomato juice has 20*90/100=18 liters of water and 2 liters of tomato.
  As tomato puree has 80% content of tomato, so 2 liters of tomato from 20 liter juice corresponds to 80% so tomato purees that can be obtained=100*2/80=2.5

• Tomato with 90% water is tomato juice and with 20% water is puree so if we reduce 70% water from tomato eith 90% water it becomes tomatoo with 20% water i.e tomato puree
  70/100*20 lit= 14 lits of water so remaining 6 lit is puree tomato
