Read Solution (Total 3)
-
- ANS : 8 people
total bill is = 4800
let us assume there r "x" no of people..
then each person should pay=4800/x
if there are 4 more people then each should pay=4800/(x+4)
Given that if there are 4 more people then 200 rs reduced for each person
Hence (4800/x)-(4800/(x+4))=200
BY solving we will get x^2+4x-96=0.
by solving above equation we will get x=8,x=-12,neglect negative value..
finally we will get x=8..................
