Farid works from 9 am to 3 pm = 6 hours
Farid can complete the job in 12 hours. So, in 6 hours, he can complete 6/12 or 1/2 of the job. Now, Jibon has to complete the rest 1/2 of the job. But, he can complete the job in 8 hours. So, he will take 8/2 or 4 hours only to complete the rest of the job. If Jibon starts working from 4 pm, the job will be completed by 8 pm.
