- Anand finishes a work in 7 days, Bittu finishes the same job in 8 days and Chandu in 6 days.
Question 1:
Anand finishes a work in 7 days, Bittu finishes the same job in 8 days and Chandu in 6 days. They take turns to finish the work. Anand on the first day, Bittu on the second and Chandu on the third day and then Anand again and so on.On which day will the work get over?
A. 3
B. 7
Feedback In the 1st day Anand does 1/7th of total work similarly, Bithu does 1/8th work in the 2nd day
hence at d end of 3 days, work done = 1/7+1/8+1/6=73/168
remaining work = (168-73)/168 = 95/168
again after 6 days of work, remaining work is = (95-73)/168 = 22/168 and hence Anand completes the work on 7th day
hence at d end of 3 days, work done = 1/7+1/8+1/6=73/168
remaining work = (168-73)/168 = 95/168
again after 6 days of work, remaining work is = (95-73)/168 = 22/168 and hence Anand completes the work on 7th day
