A tells B when I was half of your present age you were 1/4th of my present age. If A present age is 36, what is B present age?

• 30 years
  
  My present age is 36 and your present age is x.
  then
  when you(B)were 36/4 = 9 yrs old, my age (A)was x/2 years
  so
  (x/2) -9 = 36-x
  x-18 =72-2x
  3x= 90
  x= 30 years

• Ans:30 years
  At present A age=36yrs
  let B age =B yrs
  In past A's age= B/2 years
  B's age=A/4 =36/4=9 years
  Difference of ages of A and B will be same at any year
  Therefore,
  36-B=(B/2)-9
  45=3B/2
  B=30
