the large container, it takes the same amount of time to become empty as the smaller ones, and
all three containers have to be refilled every second day.
How many days will he be able to feed the birds for?
A. 12 days
B. 20 days
C. 24 days
D. 30 days

Can anyone explain?
Respected Sister,
According to me the answer should be option c.
Explanation: Step by Step below
The total capacity of the feeders is 150+150+450=750grams
The feeders need to be refilled after every 2 days so....
the Demand per day = 750grams/2 = 375 grams per day
Total Supply = 9kg = 9000grams
Total Days he can feed the birds = 9000grams/375 grams per day = 24days.
I hope I explained it well enough for you to grasp the concept.
