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?

[gauravgundal]

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
