mani's one day's work = 1/5
bijoy's one day's work = 1/6
thus, their one day work if they work together = 1/5+1/6 = 11/ 30
therefore the number of days taken to compete the work together = 1/11/30 = 30/11
hence they take 30/11 days.

In 5 day mani can do a work = 1part
In 1 day mani can do a work = 1/5part
In 6 day Bijoy can do a work = 1part
In 1 day Bijoy can do a work = 1/6part
In 1 day both Mani and Bijoy can do a work = 1/5 + 1/6
=11/30
Together 11/30 part of the work can be done in = 1 day
Together 1 part of the work can be done in = 1÷11/30
= 30/11
= 2-7/11

In 6 day Bijoy can do a work = 1part
