Solution:
Given:
30 litres of water-milk mixture contains 30% of water. So, the mixture contains,
Water = 9 litres and Milk = 21 litres
Now 10 litres of water is added to the mixture,
=> Water = 19 litres, Milk = 21 litres and the Mixture = 40 litres.
Percentage of water in new mixture = (19/40) × 100
= 95/2 %
= 47½ %
So, the correct option is D). 47½%
