1200 soldiers in a fort had enough food for 28 days. After 4 days, some soldiers left and the food then lasted 32 more days. How many soldiers left?

1. Total food = 1200 x 28 = 33600 soldier-days. Used in 4 days = 1200 x 4 = 4800; remaining = 28800. 2. Remaining food lasts 32 days, so men = 28800 / 32 = 900. 3. Soldiers who left = 1200 - 900 = 300. _Source: RRB Group D CEN-02/2018 PYQ, Q.41._
