Question

If 56 men can do a piece of work in 42 days, then in how many days will 48 men complete the same work ?

Answer 1

$\to$ Given, $56$ men can do a piece of work in $42$ days.

$\therefore 1$ man can do the same work in $\frac{42}{56}$ days.

$\therefore 48$ men can do it in $\frac{42\times 48}{56}$ days

$=36$ days

$\therefore 48$ men can do it in $36$ days.
