heinz produces tomato pure by boiling tomato juice.the tomato pure has only 20% water while tomato juice has 90% water.how many liters of tomato pure will be obtained from 20 liters of tomato juice?
options:
a) 2, b)2.4 c)2.5 d) 6 liters.

• answer 2.5
  
  20 liters of juice contains 18 liter water and 2 liter tomato pure.
  
  now let x liters of tomato pure be produced ,then
  
  x- 20x/100 = 2
  
  80x/100=2
  
  x= 2*100/80 =2.5

• ANS : c) 2.5
  20 lit juice contain 20*10/100 =2 lit tomato pulp.
  now tomato pure has 80% of tomato pulp..
  so by using 2 lit pure pulp we can produce
  2/80% =2*100/80 = 2.5 liters..

• 1 liter of tomato pure = (800ml of tomato + 200ml of water)
  so 1 liter leads to 800ml tomato,
  how many liters leads to have 2000ml of tomato...????
  
  so ans is (2000*1)/800
  
  ans is 2.5

• tomato pure-20% water, 80% tomato
  tomato juice-90% water, 10% tomato
  water in 20 lit of tomato juice-90% of 20=18 lit
  so,tomato=2 lit
  80 lit of tomato used to obtain 100 lit of tomato pure
  1 lit of tomato used to ....... 100/80 lit.....
  2 lit ......................... 100/80*2=2.5 lit

• let x be the total amount of tomato pure to be produced...then x- 20x/100(water in tomato pure) = 2(pure pulp).
  thus...solving...x=2.5 ltr

• 20 liters of tomato juice contains 18 liters of water+2 liters of tomato juice
  ------------------------
  but for a tomato puree it must contain only 20% water so
  90%---------------18liters
  20%--------------(20*18)/90=4liters
  so overall 4liters+2liters=6liters

• Suppose in 1 Liter tomato juice 0.10 L tomato + .90 L water.
  after boiling only 0.20 L water remains. It means 0.03 L pure juice
  remains out of 1.00 Liter tomato juice. So, in 20 Liters tomato juice
  
  pure juice = 20 * 0.03
  6.00 Liters.

• 20l juice=>18l water + 2 lit pure
  since-80l pure=>20l water
  =>1lit pure=.5 liter water
  =>total pure=2+.2=2.5l

• 20 litres juice contain 10% Tomato, i.e.
  20L juice=(20*10)/100 = 2L Tomato
  Tomato puree contains 80% of water and 20% tomato.
  This 80% tomato = 2L (which is contained by 100 puree)
  So, Now this 2 L Consist 80% in puree
  Thus, total puree will be,
  2/.8 = 2.5L.

• 2 liter is the pure tomato juice but for tomatoo puree it must contain 20% of water so 20% of 2 is 0.4 liters so the answer would be 2.4 liters....

• tamato juice = 20 ltr = (2ltr tamato + 18ltr water) as it contain 90% water
  by boiling content of tamato will remain same
  tamato puree = (2ltr tamato + Xltr water)
  2+ X is 100 % out which X is 20%
  so 2 is 80%
  and 100% will be 2.5ltr
  ans 2.5ltr
