In a mixture of 75 litres, the ratio of milk to water is 2 : 1. The amount of water to be further added to the mixture so as to make the ratio of the milk to water 1 : 2 will be
-
- 45 litres
- 60 litres
- 75 litres
- 80 litres
Correct Option: C
In 75 litres of the mixture,
| Milk = | × 75 = 50 litres | |
| 3 |
| Water = | × 75 = 25 litres | |
| 3 |
Let x litres of water be added.
Then,
| = | ||
| x + 25 | 2 |
⇒ x + 25 = 100
⇒ x = 75 litres
