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
