.A mixture of 66 litres of milk and water are in the ratio of 5 : 1, water is added to make the ratio 3 : 5. find the quantity of water added.
■a) 20 litres
■b) 18 litres
■c) 22 litres
■d) 24 litres

• let k be a integer constant then 5k+k=66
  =>k=11
  so initially there is milk of 55 lts. an and water of 11 lts.
  now we have to add water of x lts. to make the ratio 3:5
  so 55/(11+x)=3/5
  =>275=33+3x
  =>3x=242
  =>x=242/3=81 lts approximately
  so either the question is wrongly asked or option is not there....
  
  if it is 5:3 then
  55/(11+x)=5/3
  =>11/(11+x)=1/3
  =>33=11+x
  =>x=22 lts....
  so the required addition of water is 22 lts....

• let the amount of milk be 5x litres and water be x litres. then 5x+x=66. so x=11. so there is 55 litres milk and 11 litres water. let y litres water is added. so 55/(11+y)=5/3. so y=22. so ans is 22 litres

• 66 LITS MIXTURE
  MILK IN 66 LIT OF MIXTURE=66*(5/6)=55
  WATER IN IT=66-55=11
  55/(11+X)=5/3
  X=22 LIT(ANS)

• ANS:22 BUT QUATION IS NOT CORRECT HERE CHANGED RATIO IS 5:3 NOT 3:5

• Either question is wrong or options are wrong.
  correct solution is...
  initially milk=55l and water=11
  let added quantity of water =x
  55/(11=x)=3/5
  than x=81 approx
  if ratio is 5:3 than ans is
  55/(11+x)=5/3
  x=22
  ans
