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.
