The ratio of milk and water in mixtures of four containers are 5:3, 2:1, 3:2 and 7:4 respectively. In which container is the quantity of milk, relative to water, minimum?

In first container quantity of milk relative to water is $$\frac{5}{3} \times100$$ = 166.65%
In second container quantity of milk relative to water is $$\frac{2}{1} \times100$$ = 200%
In third container quantity of milk relative to water is $$\frac{2}{1} \times100$$ = 150%
In fourth container quantity of milk relative to water is $$\frac{7}{4} \times100$$ = 175%
hence third container has least ratio
