If five appraisers can work 4800 parcels at a rate of 15 parcels each per day, how many days will it take to finish?

To determine the number of days needed to complete the appraisal of 4800 parcels using five appraisers working at a rate of 15 parcels each per day, we first calculate the total daily output of all appraisers combined.

Each appraiser appraises 15 parcels per day, so for five appraisers, the total number of parcels they can appraise per day is calculated as follows:

Total parcels per day = Number of appraisers × Parcels per appraiser per day

Total parcels per day = 5 appraisers × 15 parcels/appraiser = 75 parcels per day.

Next, we need to find out how many days are required to appraise all 4800 parcels. This is done by dividing the total number of parcels by the daily output:

Number of days to finish = Total parcels / Total parcels per day

Number of days to finish = 4800 parcels / 75 parcels per day = 64 days.

Therefore, it will take 64 days for the five appraisers to finish their work on all 4800 parcels.
