A wizard named Nepo says "I am only three times my son's age. My father is 40 years more than twice my age. Together the three of us are a mere 1240 years old." How old is Nepo?

• nepo's age=x yr
  nepo's son's age=x/3 yr
  nepo's father's age=2x+40 yr
  total age=1240
  x+x/3+2x+40=1240
  3x+x+6x+120=1240*3
  10x=3720-120
  x=360
  Hence nepo's age is 360 yr

• nepo's son's age=>x
  nepo's age=>3x
  nepo's father's age=>2(3x)+40
  so total==> 6x+40+3x + x=1240
  x=124
  nepo's age==> 3x==>124*3=372
