a mixture of 80 liters of milk and water contain 10% water how much water must be added to make water 20% in the new mixture?

• 10 ltr of water is to be added.
  At present there is 72 ltr milk and 8 ltr water.
  ow 72 ltr milk should be 80% of mixture in new case. Then
  total mixture = 72/0.8= 90 ltr
  
  so 10 ltr water is to be added.

• 8 lit of milk is present mixture.
  let x lit of water is added. so new mixture has 80+x lit and water content is 8+x lit. given water content is 20% of new mixture i.e 80+x lit.
  so (80+x)*20/100=8+x =>80+x=40+5x =>x=10 lit.
  so 10 lit of water has to added.

• mixture of water and milk= 80L
  % of water = 10%
  therefore amount of water= 80*10/100 = 8L
  water should be added to make it 20% water,
  Let amount of water added be 'x'
  Now, total mixture of water and milk= 80+x
  amount of water added= 8+x
  % of water in mixture=20%
  therefore,
  ((8+x)/(80+x))*100=20
  40+5x=80+x
  4x=40
  x=10 liters

• it is so easy question,
  80 liter mixer in which 72 liter is milk and 8 liter is water .
  
  now , water is add for example" x "liter add so that it is 8+x
  
  new mixture content 20% of the water so it is about 20 liter water and 80 liter milk right
  
  
  
  so take ratio 72/(8+x) =80/20
  
  
  so x=10 liter

• In 8ol mixture,
  Water= 10% = 8l
  Milk= 90% = 72l
  As water is only added, the quantity of milk remains constant.
  Let quantity of new mixture be "x"
  In new mixture, water=20% of x
  therefore milk=80% of x = 72l
  therefore, x=(100/80)72l
  x=90l
  Quantity of water in new solution = 20% of 90l
  = 18l
  Therefore, quantity of water to be added in the solution = (18-10)
  = 8l
  a= 8l

• initial water=10*80/100=8ltrs
  milk=80-8=72ltrs
  72/8+x=80/20
  =>x=10
  so 10 ltrs of water to be added to make new mixture contain 20% water

• 10 liters of water must be added to make 20% of 90 litres mixture..
  let x be added this implies 20% of 80+x =8+x..
  sloving this gives x=10.

• in 80 litres water is 10% or 8 litres
  20% of 80 litres is 16 litres
  To make 8 litres to 16 litres of water,add 8 more litres of water

• in 80 lts 90% of milk ie 72 lts....so 8 lts of water
  to make 20% of water...add 6.4 lts of water...
  cos 72 lts remain same nd contribute 80% of total so 14.4 lts of water makes 20%....so 14.4-8=6.4...

• In 80 liters of mixture milk and water are in the ratio of 90:10, means 72lts of milk and 8lts of water if we want to increase water to 20% then 80/20=72/x
  then x=72*20/80=18 lts so need to add another 10 lts of water so the water % will be 20% in the new mixture

• 10% of 80 liters is 8 liters
  let x to be added then
  by adding it turns to 20%
  and mixture of 20 liters also increses so
  8+x/80+x=20%
  solving we get ans

• Given :
  mixture of 80 liters
  contains 10% water means (10% of 80)=8 liters
  80-8=72 liters of milk
  water quantity to be increased = 20%
  so milk has to be of 80% then in mixture
  
  both % ratio=4 : 1
  let water to be added x
  (72/8+x)=4/1
  x=10 liters

• mixture of water and milk= 80L
  % of water = 10%
  therefore amount of water= 80*10/100 = 8L
  water should be added to make it 20% water,
  Let amount of water added be 'x'
  Now, total mixture of water and milk= 80+x
  amount of water added= 8+x
  % of water in mixture=20%
  therefore,
  ((8+x)/(80+x))*100=20
  40+5x=80+x
  4x=40
  x=10 liters
