Question

If one rooster can wake up 10 hens, then how many hens can 3 roosters wake up?

It's not 30, I have an online correcting machine. I tried 30, it said it was wrong.

Answer 1

10 hens
there are only 10 hens so it cant wake up more

Answer 2

Rooster is an adult male chicken. To wake up hens, a rooster must crow. When a rooster crows, he will wake up all the birds available. So, even if three rooster crows, they will wake same amount of birds, that is all the birds.

Hence, if one rooster wakes up 10 hens.

3 roosters will wake up just 10 hens
