Jet airlines have business and economic class in planes to New York. On 2nd of Jan, number of passengers in business and economic class were 3 : 7.the fare charged for business to economic class is in the ratio 5 : 3. If the total fare collected from these classes were Rs. 241920, how much fare was collected from economic class? Correct Answer 141120

⇒ Passengers in business : economic class = 3 : 7

⇒ Fare in business : economic class = 5 : 3

Suppose 3x and 7x passengers travel by business and economic class respectively and 5y and 3y is the fare collected per business class and per economic class passenger respectively.

⇒ Fares of 3x passengers : fares of 7x passengers = 3x × 5y : 7x × 3y = 5 : 7

⇒ Total fare collected was Rs. 241920

∴ Fare collected from economic class = 7/(7 + 5) × 241920 = 141120

Courses of action: I. The change would bring respite for passengers and save them from being stuck in an aircraft for long durations in case of fog or extreme weather conditions. II. The airline industry’s response to the proposal has been mixed, with some calling it a good move and others saying airlines should not be penalised for infrastructure constraints that often lead to delays.  III.
