Q. Suppose that a building will be completed by 25 worker for 30 days, if we want the building completed in 15 days how many additional worker needed ....
Calculate Total Worker-Days: First, let's figure out the total worker-days needed to complete the building. This is the number of workers times the number of days they work.So, 25 workers for 30 days is 25×30 worker-days.
Determine Total Worker-Days: Now, we got 25×30=750 worker-days. This is the total amount of worker-days needed to finish the building.
Calculate Number of Workers: If we want the building completed in 15 days, we divide the total worker-days by the new number of days to find out how many workers we need.So, 750 worker-days divided by 15 days equals to the number of workers needed.
Find Additional Workers Needed: Doing the division, 750/15=50 workers are needed to complete the building in 15 days.
Find Additional Workers Needed: Doing the division, 750/15=50 workers are needed to complete the building in 15 days.But we already have 25 workers, so to find out how many additional workers we need, we subtract the original number of workers from the new number of workers.So, 50−25=25 additional workers needed.
