There are 5 passengers and 4 parachutes. The first passenger is Barack Obama, who takes a parachute on the grounds of being "the president of America". The second passenger, Mohammed Ali, takes a parachute on the grounds of being "a famous boxer". The third passenger, Donald Trump, takes a parachute on the grounds of being "the smartest man in the world!" This leaves a little girl and an old lady. The girl wants the old lady to have a parachute. The lady says "you should take it, dear. You have longer on this world than I do." The girl says back "there's two parachutes. The smartest man in the world took my backpack."
EDIT: next time get the numbers right
