Question

In an army camp, there were provisions for 425 men for 30 days. How long did the provisions last for 375 men?

Answer 1

Number of days for which provisions last for 425 men = 30 days

Number of days for which provisions last for 1 men = 30 × 425 = 12750 days. (less men means more days)

Number of days for which provisions last for 375 men = `12750/375` = 34 days

Hence, provisions will last for 34 days for 375 men.
