$A$ can finish a work in $18$ days and $B$ can do the same work in $15$ days. $B$ worked for $10$ days and left the job. In how many days, $A$ alone can finish the remaining work?

$A$ works twice as fast as $B$. If $B$ can complete a work in $12$ days independently, the number of days in which $A$ and $B$ can together finish the work in:

$A$ and $B$ can complete a work in $15$ days and $10$ days respectively. They started doing the work together but after $2$ days $B$ had to leave and $A$ alone completed the remaining work. The whole work was completed in:

$A$ does $80$% of a work in $20$ days. He then calls in $B$ and they together finish the remaining work in $3$ days. How long $B$ alone would take to do the whole work?

Twenty women can do a work in sixteen days. Sixteen men can complete the same work in fifteen days. What is the ratio between the capacity of a man and a woman?

$4$men and $6$ women can complete a work in $8$ days, while $3$ men and $7$ women can complete it in $10$ days. In how many days will $10$ women complete it?

$A$ can finish a work in $24$ days, $B$ in $9$ days and $C$ in $12$ days. $B$ and $C$ start the work but are force to leave after $3$ days. The remaining work was done by $A$ in:

$A$ and $B$ can do a piece of work in $30$ days, while $B$ and $C$ can do the same work in $24$ days and $C$ and $A$ in $20$ days. They all work together for $10$ days when $B$ and $C$ leave. How many days more will $A$ take to finish the work?

$X$ can do a piece work in $40$ days. He works at it for $8$ days and then $Y$ finished it in $16$ days. How long will they together take to complete the work?

$A$ and $B$ can do a work in $8$ days, $B$ and $C$ can do the same work in $12$ days. $A,B$ and $C$ together can finish it in $6$ days. $A$ and $C$ together will do it in:
