A crew of 3 workers needs 3 weeks and 2 days to complete a project.

Because the workers have no union protections, adding more workers is not expensive. On the other hand, the capitalists are very aware that “time is money”. They hope to make a faster profit by putting more workers on the project.

They offer you a percentage of the increased profit if you can tell them exactly how long it would take a crew of 4 workers to complete the project, each working at the same rate as the original workers.

Note that because there are no union protections, these people must work 6 days each week.
