A certain quantity of wheat is sufficient for 200 people for 30 days. If 50 more people join them, for how many days will the same quantity of wheat last?
Show answer & explanation
Correct answer: B
Explanation
Total wheat = 200 × 30 = 6000 person-days
Now, the number of people = 200 + 50 = 250
Therefore, the number of days the wheat will last = 6000/250 = 24 days
