Heinz produce tomato pure by boiling tomato juice.The tomato pure has only 20% water while the tomato juice has 90% water.How many litres of tomato pure can be obtained by 20 litres of tomato juice.
A)2
B)2.4
C)2.5
D)6

• 20 litres of tomato juice will account for 18 litres of water(90%) 2 litres(10%) of pure tomato.
  now,if we consider the tomato pure obtained from this it will contain 2 litres of pure tomato(80%) and rest water(20%).
  A number that gives 2 as its 80% is 2.5. so, it will produce 2.5 litres of tomato pure.

• Ans is 2.4
  20 liter of juice contain 2 litre of tomato.
  now in puree there is 20% water and 80% tomato.
  Therefore dilute 2 litre of tomato with 20% water which will give 2.4 litre of tomato puree.

• 20 lit of tomato juice contain 2 lit of tomato (rest 18lit i.e 90% are water)
  Tomato puree has 80% of tomato = 2 lit
  Total Tomato puree = 2 x 100 /80 = 2.5 lit

• 20 litres of tomato juice would have 2 litre of pure juce. and tomato pure would have 20% water, hence 2*20/100 = 0.4
  now tomato pure will be 2+0.4=2.4litre
  answer is b
  correct if I m wrong:)
