As+Ls=2100
Ls=large spider as=average sized spider

Ls=20As
so
as+20as=2100
21as=2100
as=100

The average sized spider lays 100 eggs at one time

let the no. of eggs laid by average side spider=x
given, 20x= 2100
divide both sides by 20
20x/20 = 2100/20
x =105
. .
. the no. of eggs laid by an average side spider = 105 eggs
