Is it 40?

I didn't do any math, I just imagined 40 cows each eating their own bag of hay, and it taking 40 days.

40 cows eat 40 bags in 40 days, so 1 cow eats 1 bag in 40 days, so she eats 1/40 bags per day, or 1 bag in 40 days.

OA?

Badly worded question. How do you know that all the cows are eating at the same rate?
The more you look, the more you see.

No of workers is directly prop. to amount of work done
No of workers is inversely prop. to time take

so
Cow's * Time Taken/(Total bags contating husk)

Therefore

40*40/(40)=1*No of days req./(1)
Answer = 40
