Question

A milkman mixes 20l of water with 80l of milk. after selling one-fourth of this mixture, he adds a water to replenish the quantity that he has sold. what is the current proportion of water to milk ?

Answer 1

100 × 1/4 = 25 ml, not sure

Answer 2

Answer:

2 : 3

Step-by-step explanation:

As one-fourth of the solution (milk + water = 80L + 20L ) is sold, solution drawn out of it is 100 x (1/4)= 25 L

Quantity of the milk drawn out = 25 x (4/5)= 20 L

» Quantity of water drawn out= 5L

Now adding  25 L of water, quantity of water = 20 – 5 + 25 = 40L

Also, quantity of milk remaining= 80 – 20 = 60L

Required ratio= 40 : 60=
