Answer:
4 days
Step-by-step explanation:
As we know
A's one day work =1/10
B's one day work= 1/12
C's one day work = 1/15
L.C.M of 10,12 and 15 = 60
(A,B,C)'s one day work = 1/10 + 1/12+ 1/15
=6+5+4/60
15/60
=1/4
this the one day work of A,B,C,
so the total number of days to complete work is reciprocal of 1/4 which is equal to 4 days.
