Question

A alone can do a piece of work in 8 days, B alone in 10 days, and C alone in 12 days. A worked for 3 days and left. Then B and C worked together for 3 days, after which В left. The remaining work was completed by C. How long did it take to finish the work? ​

Answer 1

Step-by-step explanation:

B alone can complete it in 12 days therefore in 4 days he can do 1/3 of it and in 8 days he can complete 2/3 of total work => A can complete 1/3 of the total in 8 days(since 2/3 B will do)

B worked for 4 days => 1/3 completed

And remaining is 2/3

So A will take 16 days to complete the rest

(8 days-> 1/3

16 days -> 2/3)
