Step-by-step explanation:
A can do a piece of work in=12 days
Work done by A in 1 day=1/12
B can do a piece of work in =15 days
Work done by B in 1 day=1/15
C can do a piece of work in =10 days
Work done by C in 1 day=1/10
Work done by A,B and C together in 1 day=1/12+1/15+1/10
=1/4
Therefore time taken to complete the piece of work by A,B and C together=4 days
