Question
Ratio of the work done by P, Q and R in one day is 6:4:7
respectively. They all together can complete the work in 45 days. Q and R worked on it for 27 days. In how many days P will complete the remaining work.Solution
Let total amount work be = 45 x 17 = 765 units Amount of work done by Q and R in 27 days = 27 x 11 = 297 units Amount of work left = 765 – 297 = 468 Required time = 468/6 = 78 days
