1.	Daniel and Tarzan can do a piece of work in 70 and 60 days respectively. They began the work together, but Daniel leaves after some days and Tarzan finishedthe remaining work in 47 days. After how many days did Daniel leave?
Answer» Step-by-step explanation:Total work to be DONE = LCM(70,60) = 420 units. T can do 6 units/day D can do 7 units/day. So, Tom worked alone for 47 DAYS, i.e he finished 47*6= 282 units alone. Remaining is 420-282 = 138 units. Working together, both can finish 7+6, i.e 13 units/day. So, the remaining 138 units were finished in 138/13 = 10.61 days. Hence daniel left after 10.61 days.
