A can lay railway track between two given stations in 16 days and B can do the same job in 12 days. With help of C, they did the job in 4 days only. Then, C alone can do the job in how many days ?

C alone can do the job in 48/5 = 9.6 days! Let's say C can do the work alone in X days then; 1 day of work combined = 1/16+1/12+1/X = 1/4 by solving, we get 3X+4X+48 = 12X >> 5X=48 >> X=48/5 = 9.6 days.

A lays 1/16 distance per day; B lays 1/12 distance per day. With C, they lay 1/4 distance per day. So: 1/16 +1/12 + 1/C=1/4 3C+4C+48=12C 5C=48 C=48/5 days that it would take for C to do the job alone ☺☺☺☺
