## How do you solve man days?

The new technique that we will introduce here is the concept of expressing amount of work in terms of mandays, or woman days, as applicable. As 12 men complete the job in 24 days, the work amount is 12×24=288 mandays. The concept of 1 manday work is simply the amount of work that 1 man will be able to do in 1 day.
