In a garrison, there was food for 1000 soldiers for one month. After 10 days, 1000 more soldiers joined the garrison. How long would the soldiers be able to carry on with the remaining food?

- 10 days
- 25 days
- 20 days
- 15 days

**Answer**

After 10 days, the remaining food would be sufficient for the 1000 soldiers for 20 more days.

If 1000 more soldiers are added, then it will be sufficient for only 10 days as the number of soldiers is doubled, the days are halved.

**The correctÂ option is A.**
