The ratio of milk and water in mixture 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 ?

Answer: Option C

∴According to the question,
Container :
$$\begin{array}{rl}& \text{I}\text{II}\text{III}\text{IV}\\ & \text{M}:\text{W}\text{M}:\text{W}\text{M}:\text{W}\text{M}:\text{W}\\ & 5:32:13:27:4\end{array}$$

$$\begin{array}{rl}& \mathbf{Container}(\text{I}):\\ & \frac{\text{Milk}}{\text{Water}}=\frac{5}{3}=1.67\\ & \\ & \mathbf{Container}(\text{II}):\\ & \frac{\text{Milk}}{\text{Water}}=\frac{2}{1}=2\\ & \\ & \mathbf{Container}(\text{III}):\\ & \frac{\text{Milk}}{\text{Water}}=\frac{3}{2}=1.5\\ & \\ & \mathbf{Container}(\text{IV}):\\ & \frac{\text{Milk}}{\text{Water}}=\frac{7}{4}=1.75\end{array}$$

∴ The quantity of milk relative to water minimum in container third.
