let total price be x
let y part is betted on race,if she wins she gets betted money as well as 12 times of betted money.
that is
(recieving money)12 times of batted money=12.x.y
hence eqaution becomes 12.x.y+x(his total money)=8.x
y=7/12;
that means in 5:7;


if any confisuion ask me on [email protected]
