    How long will it take workers A and B, together, to finish a job which can be done by A alone in 6 days and by B alone in 4 days?

    Solution:

    Together: 1A+1B=1T

    Where: A are the number of days A can finish the job alone . B are the number of days B can finish the job alone. T are the number of days A and B can finish the job together.

    16+14=1T

    512=1T

    T=125=2.4 days
