In a mixture of 25 litres, the ratio of acid to water is 4 : 1. Another 3 litres of water is added to the mixture. The ratio of acid to water in the new mixture is
-
- 5 : 2
- 2 : 5
- 3 : 5
- 5 : 3
Correct Option: A
In 25 litres of mixture,
| Acid = | × 25 = 20 litres | |
| 5 |
Water = 5 litres.
After adding 3 litres of water, quantity becomes 8 litres
∴ New ratio = 20 : 8 = 5 : 2
