lottery service query

This is for prvisional payment for lottery agents...

1. Rs 6000/- on every Rs 10 Lakh (or part of Rs 10 Lakh) of aggregate face value of lottery tickets printed by the organising State for a draw If the lottery or lotteryscheme is one where the guaranteed prize payout is more than 80%

2. Rs 9000/- on every Rs 10 Lakh (or part of Rs 10 Lakh) of aggregate face value of lottery tickets printed by the organising State for a draw If the lottery or lottery scheme is one where the guaranteed prize payout is less than 80%

my question is what about the 80 percent payout ??
