Answer 2

The proportion of milk and water is 89.9% and 11.1% respectively.

Step-by-step explanation:

The cost of the milk is Rs. 18 per liter

The reduced cost of the milk is Rs. 16 per liter

The cost that is need to be reduced is:

⇒ Rs. 18 - Rs. 16 = Rs. 2 per liter

Now, the milk for Rs.2 is given as:

(2/18 × 100)% = 1/9 × 100 = 11.1%

Thus, to reduce the cost of the milk to Rs. 16 per liter, the milk solution should contain 11.1% of water and 89.9% of milk.
