In a fort,300 men had provisions for 90 days.After 20 days,50 men left the fort.How long would the food last at the same rate?
Please help with a hint.
+36914 300 men x 90 days = 27000 man- days of provisions
300 men x 20 days = 6000 man days of provisions leaving 21000 man days of provisions
21000 m-d / 250m = 84 days remaining
