Question

A garrison of 500 men had provision for 24 days. However, a reinforcement of

300 men arrived. How long the food will last?​

Answer 1

Option D; After 3 days, the garrison of 500 persons had provisions for (27-3) = 24 days. a reinforcement of 300 persons have come, so now there are total 800 persons. So, the provision for them is (24 * 500 / 800) = 15 days.
