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.

O 10100

O 10010

O 110110

O 110111

• 110110 = 54 years
  
  If my present age is I and son's age is S, then
  I=3S
  and
  I-9 = 3*(S-9)
  
  solving these, we get I =54 yrs.

• (X-9)=5*(Y-9)
  and X=3*Y
  
  on solving we get X=54
  in Binary it'll be 110110

• considering son's age as x hence father's age would be 3x....
  9 years ago....a/q
  3x-5=5(x-9)
  or,x=18(son's age) father's age=54.....in binary form it is 110110

• 9 years ago==> father: 5x and son: x
  present F: 5x+9 and S: x+9
  according to condition 5x+9=3(x+9)
  x=54
  and its binary conversion : 110110
