Final answer:
To complete the same job in 3 days instead of 5 with 12 workers, 20 workers would need to be hired.
Explanation:
To solve this problem, we can use the formula: workers × days = constant work units. In the initial scenario, 12 workers * 5 days = 60 work units were needed. To calculate the number of workers needed for the same work in 3 days, we use the formula: 60 work units / 3 days = 20 workers required. Therefore, 20 workers would need to be hired to complete the job in 3 days.
