Answer:
7 days
Step-by-step explanation:
Let the total work be completed in "x" days.
Therefore,
A worked for (x-5) days
B worked for (x-5+2) = (x-3) days
C worked for x days
Now,
(x-5)/10 + (x-3)/12 + x/15 = 1
Solving the above equation, we get "x" = 7
Hence, total time taken to complete the work is 7 days.
