Question

85 litres of a mixture contain milk and water in the ratio 27:7. How much more water is required to be added in the mixture, so that the resulting mixture contains milk and water in the ratio 3:1?

Accepted Answer

D. Initial milk = $\frac{27}{34} 	imes 85 = 67.5$ litres, water = 17.5 litres. In new ratio 3:1, milk remains 67.5 litres. Water needed = $\frac{67.5}{3} = 22.5$ litres. Water to add = $22.5 - 17.5 = 5$ litres.
