Raja can do 1/4 of a job in 4 days and Mohan can do 1/5 of the job in 4 days. If both work together, how long will they take to complete the entire job?
Raja's daily work rate is 1/16 of the job (1/4 divided by 4 days), and Mohan's daily work rate is 1/20 of the job (1/5 divided by 4 days). When they work together, their combined daily work rate is 1/16 + 1/20 = 9/80 of the job.
To complete the entire job, it will take them 80/9 days, which is approximately 8.89 days.
