Answer:

48/5 days

Step-by-step explanation:

A's one day work =1/16

B's one day work=1/12

(A and B)'s one day work= 1/16+1/12

=3+4/48

=7/48 ........(1)

now

(A+B+C)'s one day work =1/4

C' one day work= 1/4-(A+B)'s one day work

= 1/4-7/48

=12-7/48

=5/48

Hence C alone can finish the work in 48/5 days.
