Question

If $24$ men can finish a piece of work in $15$ days, how many men will be needed to finish it in $40$ days?

Answer 1

Since, to finish a piece of work in$15$ days, the number of men required = $24$

So, to finish the same piece of work in$1$ days, the number of men required = $24\times 15=360$

So, to finish the same piece of work in $40$ days, the number of men required = $\frac{360}{40}=9$

Hence, $9$ men required to finish the same piece of work in $40$ days,
