Question

In a mixture of 28 litres, the ratio of milk and water is 5 : 2. Another 2 litres of water is added to the mixture. Find the ratio of milk and water in the new mixture.

Answer 1

Total mixture = 28 litres

Milk : Water = 5 : 2

Step 1: Find the quantity of milk and water

Total parts = 5 + 2 = 7

Milk

`5/7 xx 28` = 20 litres

Water

`2/7 xx 28` = 8 litres

Step 2: Add 2 litres of water

8 + 2 = 10 litres

Step 3: Find the new ratio

New Ratio = `("Milk Volume")/("Water Volume")`

= `20/10`

= `2/1`

The new ratio of milk and water is 2 : 1.
