| Suppose 1.5 liters of milk costs Rs 30 and we add some water to it. For what ratio of water and milk will the mixture cost Rs 15 per liter? |
3:5 5:3 3:1 1:3 |
| 1:3 |
| 1.5 liters of milk costs Rs 30 , So 1 liter will cost Rs 20 let C = Rs. 0 / liter , D = Rs. 20 / liter and M = Rs. 15 / liter Then the ratio of mixes is (D-M): (M-C) |
