Dear all,

I don't understand the logic of this question at all. The book says there are totally 120 surviving the first year but the answer only counts the hatched goose eggs. Why don't they count the 1/3 goose eggs that never got hatched?

I am looking forward for your helps. Thank you so much.

Let total number of eggs laid=x
Hatched=2/3x
Survived 1st month=3/4*2x/3=x/2
Survived 1st year=x/2*2/5=x/5
Now x/5=120
x=600
