Ratio of the work done by P, Q and R in one day is 7:3:8 respectively. They all together can complete the work in 42 days. Q and R worked on it for 21 days. In how many days P will complete the remaining work.
Let total amount work be = 42 x 18 = 756 units Amount of work done by Q and R in 21 days = 21 x 11 = 231 units Amount of work left = 756 – 231 = 525 Required time = 525/7 = 75 days
