A can do the work in 12 days
⇒ 1 day = 1/12 of the work
B can do the work in 18 days
⇒ 1 day = 1/18 of the work
A, B and C can do the work in 4 days
⇒1 day = 1/4
Find the time C needed if he works alone:
1 day = 1/4 - 1/8 - 1/12 = 1/24
1/24 of the work = 1 day
24/24 of the work = 1 x 24 = 24 days
Answer: C can do the work in 24 days
