Question

4. If 5 men can build a wall in 12 days, how many
men can build it in 10 days?​

Answer 1

Answer:

work capacity of 5 men

$\frac{1}{12}$

Work capacity of a single man .

$\frac{1}{12 \times 5} = \frac{1}{60}$

Let the x men complete the work in 10 days . work capacity of x mens

$= \frac{x}{60} = \frac{1}{10} \\ \\ x = \frac{60}{10} = 6 \: men$
