Answer:
Take the total amount of time taken as 1/X.
Step-by-step explanation:
So the total time would be:
X/8 + X/12 + X/15
Take LCM;
10X+15X+8X divided by 120.
33X/120=11/40.
Since we took 1/X so the answer would be the reciprocal of 33/120.
we would get 40/11 as the answer.
Therefore to finish the work they would take 40/11 days.
I hope this is the answer you are looking for.
