Answer:
bispha gets 10
Step-by-step explanation:
let total money be x
Alan gets 1/8 of x = x/8
bispha gets 1/2 of x =x/2
rest of the money = total -shared money
shared money = x/8 + x/2
rest = x - 5x/8= 3x/8
Chan share = 3x/8
Alan = x/8
2.50 = x/8
x= 2.50×8= 20
total money is 20
bispha gets x/2 =20/2=10
