A group can charter a particular aircraft at a fixed total cost. If 36 people charter the aircraft rather than 40 people, then the cost per person is greater by $12. What is the cost per person if 40 people charter the aircraft?

• If x is cost per person, then
  
  40*x = 36( x+12)
  
  SOLVING THIS, WE GET
  
  x = Rs 108.

• if cost per person in case of 40 is x, it becomes x+12 in case of 36...hence
  40x = 36(12+x)
  => 4x= 36*12
  => x=108
  
  cost of plane = 40x
  =40*108= $4320

• let cost per person when 40 persons are travelling be x.
  then,
  36(x+12)=40x
  on solving we get,x=108
