Question

George is 2/3th as efficient as smith and smith is th as efficient as john. George working alone is what fraction of all of them working together.

Answer 1

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Given,

George is 2/3th as efficient as smith and smith is as efficient as john,

So, the ratio of efficiency of George, Smith and John = $\frac{2}{3}:1:1$

$=2:3:3$

$\because \frac{\text{George's work done}}{\text{Total work them by all}}= \frac{2}{2+3+3}$

$=\frac{2}{8}$

$=\frac{1}{4}$

Hence, George working alone is $\frac{1}{4}$th of all of them working together.
