In a pot, there is a mixture of milk and water in the ratio 4 : 5. If it is filled with an additional 8 litres of milk, the pot would be full and ratio of milk and water would become 6 : 5. Find the capacity of the pot ?

Let the capacity of the pot be P litres. Quantity of milk in the mixture before adding milk = 4/9 (P - 8) After adding milk, quantity of milk in the mixture = 6/11 P. 6P/11 - 8 = 4/9(P - 8) 10P = 792 - 352 => P = 44. The capacity of the pot is 44 liters.
