In a camp of 36 earthquake victims, there is enough food for 20 days. If 12 more people come in, how many days will the food last?
Answer: 15 days
Explanation
Let's solve this problem:
Initially, food is enough for 36 people for 20 days.
Total food = 36 people * 20 days = 720 people-days
When 12 more people come, the total number of people becomes:
36 + 12 = 48
Now, let's find out how many days the food will last for 48 people:
720 people-days / 48 people = 15 days
