2 boys were telling each other the points they scored in a game.
John : "I lost 48 points and finally has 3/5 of points left."
Peter : "I lost 1/3 of the points and now you has 18 points less than I do."
How many points did John and Peter had at first?
John: 48 ÷ (1 - 3/5)
= 48*5/2
= 120 points
Peter: x - 1/3x = (120 - 48) + 18
2/3x = 90
x = 135 points
John: 120 points
Peter: 135 points
