a mixture contains alcohol and water in the ratio 12:5. on adding 14 litres of water , the ratio of the alcohol to the water becomes 4:3.the quantity of the alcohol in the mixture is?

• 12x ,5x
  12x:5x+14=4:3
  bysolving this x=7/2
  12(7/2)=42 Lts

• 12x/(5x+14)
  x=3.5
  ans=42 liters

• initial ratio 12x : 5 x
  new ratio 12x : 5x+14
  thus 12x/(5x+14)=4/3
  from there u get x=3/2
  thus initial alochol content = 12*3/2=18ltr

• let alcohol=x ltr
  water= y ltr.
  we can gett two equations as 5x-2y=0
  3x-4y=56
  we get x=42 n y=17.5

• 12x/(5x+14)=4/3
  12x*3=4(5x+14)
  36x=20x+56
  16x=56
  x=7/2
  
  12x=>12(7/2)=42 liters
