Solution
100 persons had food provision for 24 days. If 20 persons left the place, the provision will last for 30 days.
Explanation:
100 persons have food provision for = 24 days
1 person will have food provision for = 24 × 100 = 2500 days
If 20 persons left the place, then total left = 100 – 20 = 80 persons
Hence, 80 persons have food provision for = `2400/80` = 30 days
