You can put this solution on YOUR website!
together they can finish in 8 hours.
together they do 1/8 of the job in 1hour.
...
cousin takes 10 hours.
so cousin does1/10 of the job in 1 hour.
...
so you can do 1/8 -1/10 of the job in 1 hour.
LCD = 40
(5-4)/40 of the job you can do in 1 hour
=1/40 of the job.
so you will take 40 hours to do the job
