If 30 persons can consume 20 kg of flour in 25 days. How much of the flour will 15 persons consume in 30 days?
Answer: 12 kg
Explanation
First, find the consumption rate per person per day:
30 persons consume 20 kg in 25 days
Total consumption per day for 30 persons = 20 kg / 25 days = 0.8 kg/day
Consumption per person per day = 0.8 kg/day / 30 persons = 0.02667 kg/person/day
Now, find the consumption for 15 persons in 30 days:
Total consumption = 15 persons × 0.02667 kg/person/day × 30 days
= 15 × 0.8
= 12 kg
