Question

A,B and C can do a piece of work in 3,4, and 6 days respectively . if a left before 2 days and B joined after 3 days in how many days will the work be completed ? ​

Answer 1

Step-by-step explanation:

1day work of A = 1/3

1day work of B =1/4

1day work of C =1/6

Total work of A,B,C in 1 day = 1/3+1/4+1/6

= 3/4

since A left after working 2days

so , work done by A in 2 days = 1/3*2

= 2/3

work done left by B in 3 days = 1/4*3

=3/4

so, work would be completed in = 4/3*2/3*3/4

=2/3 days
