*In how many days would the 12 men and 12 women working together complete the work?$\text W = 288 \text = 144 \text$ Or, \text = 1 \text$, a woman achieves more, 1 woman working is equivalent to 2 men working, this is the stage when we derive the Without going into the mandays or womandays calculations, just by examining the given data we discover the crucial fact that 1 woman works double that of a man.*

Visit Stack Exchange A project can be done by 70 men in 100 days.

Crossing this boundary, the full period is broken and job is finished in 3 more days. As 40 men working together all through take 42 days to complete the job, and in the second case, every 10 days worker force reduces by 5, we can safely test for 50 days work portion completion.

This is called an with which the number of days can safely be multiplied.

There were 80 men at the start of the project but after 50 days, 20 of them had to be transferred to another project. I have encountered work problems before with the general formula $$\frac1A \frac1B \dots = \frac1T.$$ There's also problems with time involved: $$t_A\left(\frac1A \frac1B\right) t_B\left(\frac1C \frac1D\right) \dots = 1.$$ This problem incorporates people leaving, remaining days. Think about the required amount of work in man-days.

How long will it take the remaining workforce to complete the job? The project requires *100=7000$ man-days of total work.
