Answer 2

Answer: 25 litres.

Step-by-step explanation:

Given that ratio of milk and water is 5:1.

Let quantity of milk be 5x litres, and quantity of water be x litres.

After adding 5 litres of water, quantity of milk remains 5x litres and quantity of water becomes x+5 litres.

Also, ratio of milk and water is 5:2.

=> 5x:(x+5) = 5:2

By cross multiplication, 5x*2 = 5(x+5)

10x = 5(x+5)

2x = x+5

x = 5.

Quantity of milk in the original mixture is 5x = 5*5 = 25 litres.

Hence, quantity of milk in original mixture is 25 litres.
