A father is three times as old as his son. After fifteen years the father will be twice as old as his son's age at that time. Hence
the father's present age is

• let son's age=x
  father's age=3x after 15 years
  son's age=x+15
  father's age=3x+15 according to given condition
  2(x+15)=3x+15
  2x+30=3x+15
  x=15 i.e., son's age=15 and father's age=15*3=45....

• x=son's current age
  3x=father's current age
  2(x+15)=3x+15
  x=15
  3x=45
  ans=45

• f=3s
  f+15=2(3s)
  s=5,f=15

• let x=son's age so 3x=fathers age
  from given data
  3x+15=2(x+15)
  x=5
  so father's present age=15

• SON-> X
  FATHER-> 3X
  AFTR 15 YRS : 3X+15=2(X+15)
  3X+15=2X+30
  -->X=15
  FATHER'S PRESENT AGE -> 3X->3(15)=45YRS
