A does `(4)/(5)` parts of a work in 20 days and then calls B to do the work and they work together.

A can do 4/5 of a work in 20 days and B can do 3/4 of the same work in 15 days. They work together for 10 days. C alone completes the remaining work in 1 day. B and C together can complete 3/4 of the same work in:

A does (4)/(5) part of the work in 20 days and rest of the work is done by A and B in 3 days. In what time can B do the whole work.

A can do (1)/(3) of a work in 30 days. B can do (2)/(5) of the same work in 24 days. They worked together for 20 days. C completed the remaining work in 8 days. Working together A, B and C will complete the same work in:

A can do (1)/(5)th of a work in 4 days and B can do (1)/(6) th of the same work in 5 days. In how many days they can finish the work, if they work together?

A can do a piece of work in 20 days while B can do it in 30 days. Both of them start the work together and work for some time, then B leaves. If A completes the remaining work in 10 days, then find the number of days for which they worked together.

A can do a work in 25 days and B can do the same work in 20 days. They work together for 5 days and then A goes away. In how many days will B finish the work?
