9 years ago, I was five times as old as my eldest son. Today I am 3 times his age. HOW old am I now? Express my age in binary numbers

• if we considor todays sons age=x and fathers age=y
  then first equation
  y=3x
  and 9 year ago
  5(x-9)=y-9
  then put y=3x
  then we get 2x=36
  x=18
  and hence y =3x=54
  so binary representation for 54=110110 ans

• let us consider
  
  son = x yrs father(me)= 3x
  
  before 9 yrs
  
  son =x-9 father=3x-9
  
  now equate it
  
  (x-9)=5(3x-9)
  
  solve it x=18(10010) so my age is 54(110110) now convert urself it will be

• 9 yrs ago
  eldest son age be 'x'
  my age '5x'
  9 years back
  eldest son age 'x+9
  my age '5x+9'
  by the problem
  5x+9 = 3(x+9)
  x=9
  my age 5x=5*9=45
  in binary
  101101

• son age=x years
  father age=5x years 9 years ago
  now 5x+9=3(x+9)
  so x=9 years
  father age=54 years
  in binary 110110
