1. The respective ratio of milk and water in the mixture is 4 : 3. If 6 litres of water is added to this mixture, the respectively ratio of milk and water becomes 8 : 7. What is the quantity of milk in the original mixture ?
Quantity of water = 3x litres
On adding 6 litres of water, we get
∴ Required quantity of milk
= 4x
= 4 × 12
= 48 litres
Solution:
Let the quantity of milk and water in initial mixture be 4x and 3x litres.Quantity of water = 3x litres
On adding 6 litres of water, we get
∴ Required quantity of milk
= 4x
= 4 × 12
= 48 litres
