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?

25 days

20 days

15 days

10 days

Explanation:

After 10 days, the remaining food would be sufficient for the 1000 soldiers for 20 more days So, If 1000 more soldiers are added, it shall be sufficient for only 10 days (as the no. of soldiers is doubled, the days are halved)
