Provide the details in your solution. Three painters, Mike, Dan and Katy, working together can paint the exterior of a house in 10 hours. Dan and Katy together have painted a similar house in 15hours. One day, all three worked on this same kind of house for 4 hours, after which Katy left. Mike and Dan required 8 more hours to finish. Assuming no gain or loss in efficiency, how long should it take each person to complete such job alone?
