A mixture contains alcohol and water in the ratio 4 : 3. If 5 litres of water is added to the mixture, the ratio becomes 4: 5. Find the quantity of alcohol in the given mixture

• let alcohol=4x liters ; water=3x liters
  5 liters of water is added then total amount of water will be 3x+5
  => (4x/3x+5)=4/5
  => x=5/2
  So quantity of alcohol in the mixture is 4*(5/2)=10liters

• let the quantity of alcohol and water b 4x and 3x litres respectively.
  after 5 litres added....water=3x +5
  4x/3x+5=4/5
  x=2.5
  alcohol=4x=10litre

• let content of alcohol is =x, & water is y.
  given is x/y=4/3.........eq.1
  now after adding 5 liter of water it is x/y+5=4/5...........eq.2
  on solving both we get alcohol(x)=10lit. & water(y)=7.5liter

• intial the mixture is 4/3
  after adding 5 litrs of water the ratio becomes 4x/3x+5 =4/5
  ans 10 litrs

• let the common ratio be 'x'
  therefore qty of alcohol and water is 4x & 3x litres. After adding 5 litres of water the ratio becomes 4:5. Therefore (3x+5)*4= 5*4x.
  x=5/8, therefore qty of alcohol in the mixture is 2.5 litres.

• answer is 10 litres
  let us assume that content of alcohol is 4x litres and water be 3x litres. 5 litres of water is added ie., 3x+5 litres now. again the fresh ratio is 4:5, ie., 4x/(3x+5) = 4/5, on solving we get x as 2.5, so quantity of alcohol is 4(2.5) = 10 litres.

• let alcohol=3x and water =4x
  after 5 liters of water is added so,
  by taking ratio 4/5=4x/(3x+5) so that ,x=5/2
  finally total alcohol in mixture is =4*5/2=10litres

• 5 litres
  4x/(3x+5)=4/5
  x=5/4
  so alchol content 5 litres

• suppose alchl=4x ltrs ; watr=3x ltrs
  5 ltrs of water is added then total amnt of water will be=3x+5
  => (4x/3x+5)=4/5
  => x=5/2
  alcohol in the mixture is 4*(5/2)=10liters
