Problem 6 - Entrance Test

The total work needed for the project can be found by multiplying the average number of workers by the number of days: 6 workers * 10 days = 60 worker-days. With 8 workers, the number of days required would be the total work divided by the number of workers: 60 worker-days / 8 workers = 7.5 days. However, my calculations are to illustrate the method, but the formula and the provided options suggest simplification or a specific approach not directly leading to the exact provided choices. The correct approach is inverse proportionality between the number of workers and the days: if 6 workers take 10 days, then the work can be represented as 6 * 10 = 60 worker-days. For 8 workers to do the same amount of work, it would take 60 worker-days / 8 workers = 7.5 days, indicating an error in my initial explanation towards the options given. Correctly applying the formula based on the question and available choices should align with the concept that the product of the workers and days should be constant across scenarios.
