Ratio of water and milk in a container is 2 : 3. If 40 liter mixture removed from the container and same quantity of milk is added to it then the ratio of water to milk becomes 1 : 4. Find the initial quantity of mixture?

• A. 80 lit
• B. 85 lit
• C. 75 lit
• D. 90 lit

Answer: (A)

From the given data, let the initial quantity of the mixture = 5x Then, 2 x   -   16 3 x   -   24   +   40   =   1 4 8 x   -   64   =   3 x   +   16 5 x   =   80 x   =   16   lit   Then the initial quantity of the mixture = 5x = 5 x 16 = 80 lit.
