Question 30
A and B can complete a task in 40 days, B and C can complete it in 30 days while C and AÂ can complete the same task together in 24 days. How many days will each of A, B and C take to complete the task individually?
Solution
Total work that can be completed by A and B in one day = $$\frac{1}{40}$$
Total work that can be completed by A and B in one day = $$\frac{1}{30}$$
Total work that can be completed by A and B in one day = $$\frac{1}{24}$$
Total number of days each can complete in one day = $$\frac{1}{40} +Â \frac{1}{30} + \frac{1}{24}$$
