Hey User !

=) The profit of 20% came by selling added water at the same rate.

The profit of 20% came by selling added water at the same rate.Therefore, quantity of water = 20% of quantity of milk.

The profit of 20% came by selling added water at the same rate.Therefore, quantity of water = 20% of quantity of milk.Hence, quantity of water in 1 kg milk = 200 gm (20% of 1 kg)

Answer 2

Answer:

Let the Cost Price of milk be Rs. 1 per liter.

Then, Selling Price of 1 litre of mixture = Rs. 1

Gain obtained= 20%

Then, Cost Price of 1 litre of mixture = Rs (100/120)*1 = Rs. 5/6.

The ratio of water and milk = 1/6: 5/6 = 1:5
