Jawaban dan Penjelasan
Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.
Jawaban:
A contractor estimates that he can complete a job with 15 people in 40 days. After 12 days, the work stopped for 7 days due to some reason. To complete the job on time, how many more workers need to be added?
To complete the job on time, the contractor needs to add more workers to the team. If the work stopped for 7 days and there are 40 days in total to complete the job, then the remaining number of days to work is 40 - 12 - 7 = 21 days. If the contractor can complete the job with 15 people in 40 days, then to complete the job in 21 days, he needs to add 15 / 40 * 21 = 8.25 more workers. Since it is not possible to add a fraction of a worker, the contractor needs to add at least 9 more workers to the team to complete the job on time.
