 Q. The proportion of milk and water in 3 samples is $2:1$, $3:2$ and $5:3$. A mixture comprising of equal quantities of all 3 samples is made. The proportion of milk and water in the mixture is :
 ✖ A. $2:1$ ✖ B. $5:1$ ✖ C. $99:61$ ✔ D. $227:133$

Solution:
Option(D) is correct

Proportion of milk in 3 samples is $\dfrac{2}{3}, \dfrac{3}{5}, \dfrac{5}{8}$

Proportion of water in 3 samples is $\dfrac{1}{3}, \dfrac{2}{5}, \dfrac{3}{8}$

Since equal quantities are taken,

Total proportion of milk is $\dfrac{2}{3}+\dfrac{3}{5}+\dfrac{5}{8}=\dfrac{227}{120}$

Total proportion of water is $\dfrac{1}{3}+\dfrac{2}{5}+\dfrac{3}{8}=\dfrac{133}{120}$

Proportion of milk and water in the solution is  = 227:133
