Given : Pembangunan sebuah jembatan direncanakan selesai dibangun selama 30 hari oleh 28 pekerja. Karena suatu hal, setelah 8 hari bekerja pekerjaan terhenti selama 8 hari

To find : Agar pekerjaan selesai tepat waktu, banyak tambahan pekerja yang dibutuhkan adalah...

Solution:

The construction of a bridge is planned to be completed within 30 days by 28 workers. For some reason, after 8 days of work ,  work stopped for 8 days. In order for work to be completed on time, many additional workers are needed

Total Work  =  30 * 28  = 840  worker Days

Work done in 8 days  = 28 * 8  = 224  worker Days

Remaining Work = 840 - 224 = 616 worker days

Days left =  30 - 8 - 8 = 14 Days

Workers required  = 616/14  =  44

Additional worker required = 44 - 28  = 16

16 Additional workers required

Total Pekerjaan = 30 * 28 = 840 Hari pekerja

Pekerjaan dilakukan dalam 8 hari = 28 * 8 = 224 Hari pekerja

Pekerjaan Tersisa = 840 - 224 = 616 hari kerja

Sisa hari = 30 - 8 - 8 = 14 Hari

Diperlukan pekerja = 616/14 = 44

Diperlukan pekerja tambahan = 44 - 28 = 16

16 Pekerja tambahan diperlukan
