Raju can do a piece of work in 10 days and vicky in 12 days and Tinku in 15 days. They all start the work together but raju leaves after 2 days and vicky leaves 3 days before the work is completed. In how many days is the work completed?

• three together do (1/10+1/12+1/15)=1/4 part of the work.after 2 days 1/2 part done and 1/2 part left.now viky and tinku are in work.they work (1/12+1/15)=9/60 part in a day.tinku works (3/15)=1/5 part in last three days.hence work left (1/2-1/5)=3/10 part.this part of work was done by vicky and tinku in (60/9*3/10)=2days.hence work was completed in (2+2+3)=7days........
