A canister holds 36 litres of mixture of milk and water in the ratio 3 : 1. 15 litres of milk is added to the canister. The new ratio of the mixture is :
-
- 12 : 5
- 14 : 3
- 7 : 4
- 9 : 4
Correct Option: B
In original mixture,
| Milk = | × 36 = 27 litres | |
| 4 |
| Water = | × 36 = 9 litres | |
| 4 |
On adding 15 litres of milk,
Required ratio = (27 + 15) : 9
= 42 : 9 = 14 : 3
