- #5In a fort 150 men had provisions for 45 days. After 10 days, 25 men left the fort. How long would the food last at the same rate?Ans : After 10 days:
For 150 men, provision will last (45 - 10)
Days = 35days
⇒ For 1 man, the provisions will last = 150 × 35 days
And for (150 - 25) = 125 men, the provisions will last for = (150 × 35)/125
= 42 days
