a school group charters three identical busses and occupies 4/5 of the seats.after 1/4 of the passengers leave,the remaining passengers use only two of the busses.the fraction of the seats on the two busses that are now occupied.

• Let the number of seats in each bus is x
  Total Seats=3x
  Number of seats occupies=4/5*(3x)
  Remaining passengers=1-1/4=3/4
  Now occupied seats=(3/4)*(4/5)*3x=9x/5
  They use only two busses....
  fraction of seats=9x/5*(1/2x)= 9/10

• The buses each seat x passengers. You have 3 buses each 4/5 full, so your total number of passengers = 3 * 4/5 * x = (12/5)x
  
  1/4 leave, so now you are down to 3/4 of the passengers remaining, so that is (3/4) * (12/5)x = (36/20)x = (9/5)x
  
  Since these people are now on two buses, half of this number is on each bus, so each bus has (1/2) * (9/5)x or (9/10)x, so 9/10's of the seats are taken on each bus

• Total No. of passenger Occupied seats
  100% 80%
  75% ?
  60% ------ means 3/5 fraction of seats

• let us consider that each buses has the capacity to hold (x child)
  therefore total capacity of bus = 3x
  seat occupy= (4/5)*3x=12x/5
  among that group 1/4 leave= (12x/5)*(1/4)=3x/5
  remaining child=12x/5 - 3x/5=9x/5
  now we have to find fraction of seat on 2 buses that are now occupied:
  1st capacity of 2 buses =2x
  therefore:= (9x/5)*(1/2x)=9/10
