In a can, there is a mixture of milk and water in the ratio 4 : 5. If it is filled with an additional 10 litres of milk the can would be full and ratio of milk and water would become 6 : 5. Find the capacity of the can? Pick one:
A) 40 B) 44 C) 48 D) 55 E) None of these
Let the capacity of the can be T litres.   Quantity of milk in the mixture before adding milk = 4/9 (T - 10)   After adding milk, quantity of milk in the mixture = 6/11 T.   6T/11 - 10 = 4/9(T - 10)   10T = 990 - 440 =&gt; T = 55.   ANSWER:55
