Mr. Grayson wanted to have a boundary wall around his garden. He hired three laborers of the same efficiency. The three worked together for 30 days, but during their work, they all did not come for a few days as they had to attend festive occasions. One of them did not come for 10 days more than the second laborer, and the third laborer did one-third of the total work. How many more days did the first laborer not come compared to the third laborer?
