A man said to his friend, “I am three times as old as my son. Five years later I shall be two and a half times as old as my son.What is my age?”

• not 40 sir..your age is 45 years right now and your son is 15 years old...
• 12 years agoHelpfull: Yes(6) No(1)
• sir your age is 40 years right now...
• 12 years agoHelpfull: Yes(2) No(5)
• let, the age of man=x ; the age of son=y;
  x=3y.........equation(1)
  x+5=5/2(y+5)....equation(2) [two and half means=5/2]
  solving above two equations, we will get y=15
  x=15*3=45
  hence age of man and his son are 45 and 15 years respectively .
