You can put this solution on YOUR website!
If the carpenter takes 8days to finish the job, in 1 day he will do 1%2F8 of work.
Similary let the other carpenter take a days to finish the job therefore he will in one day do 1%2Fa of the work
Combined in one day they will do 1%2F8+%2B+1%2Fa+of the work in day
But we know that combined they take 4days to finish the job.SO in 1day they should do 1/4 of the work
1%2F8+%2B+1%2Fa+=+1%2F4
Can you solve for a?
