Because ticket A is expensive, so in the case of the same total amount of money, the number of people must be as small as possible, and there must be enough people to buy a ticket. Assuming that 100 tickets have been sold out, the total income is 100 * 40 = 4000 yuan, and the difference is 4340-4000 = 340 yuan, but 340 is not divisible by 30. So if you sell 2 less A tickets, there is still a difference of 340 + 2 * 40 = 420 which can be divisible by 30, 420 30 = 14.

So there is a minimum of 98 + 14 = 112 people.

Similarly, in order to increase the number of people as possible, it is necessary to make enough people who buy B tickets to train Duan Sun. Let's assume that all 100 B tickets have been sold out, then the total income is 100 * 30 = 3000 yuan, and the difference is 4340-3000 = 1340 yuan, but 1340 is not divisible by 40. Therefore, if you sell 2 less Burning Wheel B tickets, there is still a difference of 1340 + 2 * 30 = 1400 yuan, which can be divisible by 40, 1400 40 = 35.

So there is a maximum of 98 + 35 = 133 people.
