Step-by-step explanation:

50 granules was pecked by the 50th bird

Karson Hancock · Answer 2

50.

Step-by-step explanation:

As you can see the third bird pecks 60 + 40 / 2 = 50 granules. The fourth bird thus pecks 60 + 40 + 50 / 3 = 50 granules. The fifth bird pecks 60 + 50 + 50 + 40/4 = 50 granules. As you can see, it will always be 50 after this.
