The ratio of milk to water in a mixture is 2 : 3 and the ratio of water to milk in another mixture is 3 : 4. What will be the ratio of milk to water if 105 litres of each type of mixture is added to 100 litre of pure milk?
Explanation:
105 litres of each type of mixture is mixed with 100 liters of milk
∴ Quantity of milk = 2/5 × 105 + 4/7 × 105 + 100 = 202
⇒ Quantity of water = (105 + 105 + 100) - 202 = 108
∴ Ratio of milk and water in the final solution = 202 : 108 = 101 : 54.
Hence, option (e).
