What fraction of the job can the painters
get done in days?
They can do of the job
That leaves of the job left to do
----------------------------------------
It is assumed ( but they don't say it ) that the
extra painters work at the same rate as
the first
-------------------
There are painters total after
the 1st 2 days
-------------------

times as many painters can work at
times the rate, so their rate is
( 1 job ) / ( 17/5 days ) =
Now I can say:
( t is time in days )
Multiply both sides by

3 days are required to finish the job
hope I got it
