Question

4) A milkman mixes 25 litres of water with 75 litres of milk. He sells 1/5th of the mixture and
water to replenish the quantity which he has sold. What is the resultant proportion of milk to water​

Answer 1

Answer:

Resultant Milk to water ratio is 3 : 2

Step-by-step explanation:

Water to Milk ratio = 25 : 75

Total = 100 L

1/5th of Mixture = 100/5 = 20 L

Quantity of water remained =  25 - 25/5 = 20 L         -------------->(1/5 * 25)

Quantity of Milk remained  = 75-75/5 = 60 L              --------------->(1/5 * 75)

Now

Water to  milk ratio =  20 : 60

After +20 (replenish)

Water to milk ratio = 40 : 60

2:3
