Answer 2

Answer:

The ratio between water and milk is 89.9% of milk and 11.1% of water.

Step-by-step explanation:

Given:

The water and milk be mixed to reduce the price from Rs. 20 per liter to Rs. 18 per liter.

To find:

the ratio of water and milk.

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

The cost that exists required to be reduced is:

⇒ Rs. 18 - Rs. 16 = Rs. 2 per liter

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

$\left(\frac{2}{18} \times 100\right) \%$

$\Rightarrow \quad \frac{2}{18} \times 100=11.1 \%$

So to reduce the cost by 2 Rs 11.1 % of the water should be added

The proportion of milk and water will be 89.9 and 11.1 respectively

Therefore, the ratio should water and milk be mixed to reduce the price from Rs. 20 per liter to Rs. 18 per liter is 89.9% of milk and 11.1% of water.
