Answer:
total time = 3 whole 3/4
Step-by-step explanation:
A can do a piece of work = 12 days
one day work= 1/12 days
B can do a peice of work = 15 days
one day work= 1/15 days
C can do a piece of work = 10 days
one day work= 1/10 days
Time in which they work together
1/12 + 1/15 + 1/10
take the l.C.M of all the denominators
L.C.M = 60
= ( 5 + 4 + 6 )/60
= 16/60 = 4/15
now the reciprocal it
= 15/4 = 3 whole 3/4
