Question

A milkman mixes 20 litres of water with 80 litres of milk. after selling onefourth of this mixture, he adds water to replenish the quantity that he has sold. what is the current proportion of water to milk

Answer 1

Answer:

2:3

Step-by-step explanation:

Total quantity = 100 litres

the ratio of water to milk = 1:4

25% is sold.

remaining = 75 litres.

the quantity of water remaining = 75/5 = 15 litres.

quantity of milk remaining = 75*4/5 = 60 litres.

Now 25 liters of water is added.

so 40 liters of water and 60 liters of milk.

The ratio becomes 2:3
