Question

A piece of work is completed by 9 men. If only 3 men work together, what amount of the same work would be done in the same time?

• A. one-fourth
• B. one-third
• C. three-fourths
• D. one-half

Answer 1

The correct option is B

one-third

Let the work done by 3 men be x

9x = 3

x = $\frac{3}{9}$ = $\frac{1}{3}$

Therefore, only one-third work would be done by 3 men in the same time.
