    A and B together can complete a work in 30 days. They worked together for 10 days and B left the job. The remaining work is completed by A alone in next 30 days. In how many days B alone will complete the same work?

    A)  48 days                      

    B)  60 days

    C)  75 days                      

    D)  90 days

    Correct Answer: D

    Solution :

     Work done by A and B in 10 days \[=\frac{10}{30}=\frac{1}{3},\]Remaining work \[=\frac{2}{3}\] \[\because \,\,\,\frac{2}{3}\]work is done by A in 30 days \[\therefore \]  work is done by A in \[\frac{30\times 3}{2}=45\] days Time taken by B alone to complete the work \[=\frac{1}{\frac{1}{30}-\frac{1}{45}}=\]
