The Airline

Algebra Level pending

An aeroplane can carry a maximum of 200 passengers . A profit of Rs 1000 is made on each executive class ticket and a profit of Rs 600 is made on each economy class ticket. The airline reserves atleast 20 seats for executive class . However, atleast 4 times as many passengers prefer to travel by economy class than by executive class.

What is the maximum profit (in Rs) that can be made by the airline?
