In 50l can, milk and water in the ratio of 3:1. if the ratio has made 1:3 then the quantity of water that has to be added further is?
a) 100
b) 120
c) 90
d) 80

• 100 litre water is to be added.
  
  let 'x' liter water is to be added more.
  Then 1/3 = 37.5 /(12.5 + x)
  x= 100

• 50 lit = 37.5 lit of milk+ 12.5 lit of water (3:1)
  required is 1:3, we have to add water let it be x
  1/3=[37.5/(12.5+x)]
  by solving we get 100 lit
  Now
  12.5+100= 112.5
  the ratio is 37.5/112.5=1/3

• 50 liter can having 37.5 Lt milk and 12.5lt water (3:1)
  to make it 3:1 we should add the water upto water = 3 times of milk
  3*37.5=112.5
  water to be added is 112.5-12.5=100

• Assuming water to be 10 lt at start.. so milk 30 lts - 1/3 ratio
  to make the ratio opposite we have to add another 80 lts of water to make milk as 30 lts and water as 90 lts .
  which satisfies the conditon

• M:w-3:1
  Can is 50
  M:w=37.5:12.5
  37.5÷12.5+x=1÷3
  X =100

• 3x:x=milk:water
  37.5:12.5(50lit total)
  (37.5/12.5+x)=1/3
  x=100
