The hotel bill for a certain number of people for an overnight stay is Rs.4800. If there were 4 more, the bill each person had to pay would have been reduced by Rs.200. Find the number of people staying overnight.
8
Let the number of persons who stayed overnight in the hotel be x.
The amount of bill each person had to pay = Rs4800x
The amount of bill each persons had to pay when there were 4 more persons = Rs4800x+4 It is given that the amount of bill each person had to pay would have been reduced by Rs 200 if there were 4 more persons.∴4800x−4800x+4=200⇒x2+4x−96=0On solving ⇒x=8 or x=−12But,x=−12 is not possible .∴x=8
Hence, there were 8 people in the hotel.
