$\text{Total Work}=\text{20 men}\times \text{5 days}$

Now, if we want to find out how many days it will take for 10 men to complete the same work, we can set up the equation like this:

$\text{Total Work}=\text{10 men}\times \text{number of days (we want to find)}$

Since the total work remains the same in both cases, we can equate the two expressions:

$\text{20 men}\times \text{5 days}=\text{10 men}\times \text{number of days}$

$20\times 5=10\times \text{number of days}$

$100=10\times \text{number of days}$

Divide both sides by 10:

$\text{Number of days}=\frac{100}{10}=10\text{ days}$

So, 10 men would take 10 days to complete the work.
