Question

Two workers, if they were working together, could finish a certain job in 12 days. If one of the workers does the first half of the job and then the other one does the second half, the job will take them 25 days. How long would it take each worker to do the entire job by himself?

Answer 1

If one worker did the entire job by himself, it would take fifty (50) days to finish the job.

Explanation: The question tells us that if one worker were to do half of the job, then it would take twenty-five (25) days to complete. Multiply the days it takes by two (2) and you get your answer.

Edit: Both of the workers are taking 50 days to finish the job, just to clarify. (They might be robots or something if they can both do the same thing at the same rate lol)
