If 1 day’s work = 1/20, then time required to finish the job (in days) is:

🧠 Explanation:

If 1 day’s work is 1/20 of a job, the time to finish the job is 20 days. Since 1/20 represents the daily work rate, the total time is the reciprocal, 20/1 = 20 days. This work-rate problem is common in mathematics, testing efficiency calculations. It’s applicable in project management, construction, or economics, where task completion times are critical. Understanding such problems ensures accurate planning and resource allocation, enhancing problem-solving skills in academic and professional settings where time and productivity are key considerations.
