Question

6. A group of 120 men had provisions for 200 days. After 5 days 30 men
died due an epidemic. How long will the remaining food last?
​

Answer 1

Answer:

260 days

Step-by-step explanation:

• The food provision is sufficient for 120*200 = 24000 man-days.
• In 5 days the provision consumed by 120 men = 120*5 = 600 man-days.
• Remaining provisions = 24000 - 600 = 23400 man-days.
• Men remaining after 5 days = 120 - 30 = 90 men.
• The remaining provisions will last the 90 another 23400 man-days/ 90 men = 260 days.
