সঠিক উত্তর
2 (18 days)
বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
After 3 days, food having for = (30 - 3) = 27 days
After arriving 300 men, total men = (600 + 300) = 900 men
600 men can eat the food for 27 days
∴ 1 man can eat the food for (27 × 600) days
∴ 900 men can eat the food for (27 × 600)/900 days = 18 days
