In a can, there is a mixture of milk and water in the ratio 4 : 5. If it is filled with an additional 12 litres of milk the can would be full and ratio of milk and water would become 6 : 5. Find the capacity of the can?	Choose the correct choice from the following answers:
A) 40
B) 44
C) 66
D) 52
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 - 12)   After adding milk, quantity of milk in the mixture = 6/11 T.   6T/11 - 12 = 4/9(T - 12)   10T = 1188 - 528 =&gt; T = 66.   ANSWER:66
