Q. Flights A and B are scheduled from an airport within the next one hour. All the booked passengers of the two flights are waiting in the boarding hall after check-in. The hall has a seating capacity of 200 out of which 10% remained vacant. 40% of the waiting passengers are ladies. When boarding announcements came, passengers of flights A left the hall and boarded the flight. Seating capacity of each flight is two-third of the passengers who waited in the waiting hall for both the flights put together. Half the passengers who boarded flight A are women. After boarding for flight A, 60% of the waiting hall seats became empty. For every twenty of those who are still waiting in the hall for flight B, there is one airhostess in flight A. Then, what is the ratio of empty seats in flight B to number of airhostesses in flight A?

• Hall capacity 200
  10%vacant -- so 180 passengers waiting
  40% i.e 72 are women
  seating capacity of each flight = 2/3 *180 =120
  after boarding flight a, 60% i.e 60/100 *200 =120 seats became vacant
  
  so 80 people are still waiting
  i.e. 100 people boarded the flight .
  
  80/20 =4 air hostesses.
  
  120-80 = 40 empty seats in flight b.
  
  40:4 = 10:1
