How does the number of solutions for g < 99 between 20-70 compare to the number of solutions between 80-90

There are 5 times as many solutions between 20 and 70
The number of solutions between 20 and 70 is 25 times the number of solutions between 80 and 90
There are 40 more solutions between 20-70
Both are infinite

The correct answer is: There are 40 more solutions between 20-70 than between 80-90.
