In Kakegurui manga chapter 3, Yumeko bet all her 40 chips on number 24 and she claimed that if the sword happened to face up on number 24, Yuriko would lose with the total debt of 21億7000万円. How to get this number?
Based on my understanding, both players agreed to bet 40 chips in this round. So if Yumeko is lucky, she would earn 30*40=1200 chips (I assume these chips come from Yuriko's side? If so, she would lose 1200 chips in exchange). The chip difference between these two players would be (40+1200)-(40-1200)=2400. So since each chip is worth 100万円, Yuriko will lose with debt totalling 24億円...
Where did I make a mistake?
I already read this question but it didn't help much.
