# Ratio of Acid & Water is 2:1, Find Amount of Water to form ratio to 1:2

In a mixture of 60 liters, the ratio of acid and water is 2:1. What amount of water must be added to make the ratio of acid and water as 1:2?

- 60 liters
- 72 liters
- 44 liters
- 52 liters

**Answer: (1) 60 litres**

**Explanation:-
**The ratio of the acid and water in a mixture = 2: 1

Total quantity of mixture = 60 litres

Then, the of acid in the mixture = 60 x 2/3

= 40 litres

The, quantity of water in the mixture = 60 x 1/3

= 20 litres

If water 60 litres added, then the ratio will be 2: 1

Then, the new ratio of acid and water = (20 + 60): 40

= 80: 40

= 2: 1

Hence, the answer is (1) 60 litres.
