Solution
The bill is taken as whole so the bill is 1
A paid = 1/2 B paid = 1/5
C,D,E paid equal amounts.Let it be 'x' Total amount fraction = 1 So A + B + C + D + E = 1/2 + 1/5 + x + x + x = 1 (5 + 2)/10 + 3x = 1 7/10 + 3x = 1 3x = 1 - 7/10 3x = 3/10 x = 1/10
So required fraction of bill paid by C,D,E each is 1/10
