Answer and explanation

Correct answer D

In 60 litres with ratio 5 : 3, Milk = 58×60=37.5\frac{5}{8} \times 60 = 37.5 L and Water = 38×60=22.5\frac{3}{8} \times 60 = 22.5 L. For the new ratio to be 1 : 2, the total water required is 2×37.5=752 \times 37.5 = 75 L. Thus water to be added = 75−22.5=52.575 - 22.5 = 52.5 litres.
