    Three glasses of capacity 2 L, 5 L and 9 L contain mixture of milk and water with milk concentrations 90%, 80% and 70% respectively. The contents of three glasses are emptied into a large vessel. Find the milk concentration and ratio of milk to water in the resultant mixture

    A) 52 : 49             

    B)  31 : 151

    C)  125 : 51                      

    D)  121: 39

    Correct Answer: D

    Solution :

    Total quantity of milk\[=2\times 0.9+5\times 0.8+9\times 0.7=12.1\,\,L\] Milk concentration in the resultant mixture \[=\frac{12.1}{2+5+6}\times 100=75.625%\] Water concentration in the resultant mixture \[=100-75.625%=24.735%\] Milk : Water \[=\frac{75625}{24735}=121:39\]
