The men already in Garrison = 500 

Extra men = 300 

Total men now ( 500 + 300 ) = 800 men 

500 men provision 24 days 

1 men provision 24 x 500 days 

800 men provision = 24 x 500 / 800
 = 15 days

Calculation:

The initial provisions were for 500 persons for 27 days. Therefore, the total initial provisions can be calculated as:
Total provisions = 500 persons * 27 days = 13500 person-days

After 3 days, the provisions were consumed by the original 500 persons. So, the remaining provisions were for 500 persons for 24 days. The remaining provisions can be calculated as:
Remaining provisions = 500 persons * 24 days = 12000 person-days

When the reinforcement of 300 persons arrived, the total number of persons became 800. Now, the provisions need to last for these 800 persons.

Remaining days:

Now, we need to find out for how many more days the remaining food will last for 800 persons. Let's assume it will last for x days.

Therefore, the total provisions for 800 persons for x days can be calculated as:
Total provisions = 800 persons * x days = 800x person-days

Since the total provisions must remain the same, we have:
Total provisions = Remaining provisions
800x = 12000
x = 12000 / 800
x = 15 days

Therefore, the remaining food will last for 15 more days for the garrison of 800 persons.

So, the correct answer is option D) 15 days.
