algebra precalculus - In how many days Y alone finish the work

X and Y do a piece of work in 30 days .They work together for 6 days and then X quits and Y finishes the work in 32 more days.In how many days would Y be able to finish the work alone?



note:X+Y=1/30
then X+Y=6/30=1/5 finished work
remaining 11/5=4/5 work only by Y in 32 more days
so 5432=40 days
is this correct?.
