Solution
Mixture remaining after selling 10 litres = 40 - 10 = 30 litres
Now, quantity of water in 30 litres of mixture = $\frac{15}{100} * 30$ = 4.5 litres
Milk = 30 - 4.5 = 25.5 litres
After adding 12.5 litres of water, total quantity of water = 12.5 + 4.5 = 17 litres
$\therefore$ Required ratio of milk and water = 25.5 : 17
= 1.5 : 1 = 3 : 2
