Answers
A ,B and C can do given piece of work=10
so,they can do 1/10 parts of work.
A alone can do same work =40
So, A can do 1/40 parts of work.
B alone can do same work =30
so,B can do 1/30 parts of work.
Let C alone do same work be x
so,C can do 1/x parts of work.
According to question:-
==> 1/10=A + B +C
putting the all value
Now,
1/10=1/40+1/30+1/x
1/10=7/120+1/x
1/10 - 7/120 =1/x
5/120=1/x
1/24=1/x
therefore C can do 1/24 Parts of work.
☆Answer is 24 days .
