A takes 6 days le

Answer :

Let time taken to do work by B = x

Time taken by A to finish work = x – 6


Work done by A in one day


Work done by B in one day


If both A and B work together, then work done in one day


So, we have







But, x-6>0 (as time taken by A to finish work is x-6 which should be greater than 0)


So x = 12


Therefore, time taken to finish work by B is 12 days.


Conclusion: Therefore, time taken to finish work by B is 12 days
