Explanation:

The efficiency of (A + B) = (100/36)%;
The efficiency of (B + C)= (100/24)%;
The efficiency of (A + C)=(100/18)%;
Adding above equations-
The efficiency of 2*(A + B + C)= (100/36) + (100/24) + (100/18)= (25/2)%;
The efficiency of (A + B + C) = (25/4)%.
The number of days to complete the task by all of threes = 100/(25/4) = 16 days
