61.8 years ago, Andromeda's age was twice Achilles' age. 8 years hence. Andromeda's age will be 4/3 times the age of Achilles'. Find Andromeda's present age in binary numbers.

• Let Andromeda's and Achille's present age is x and y respectively
  So 8 years before:-
  x-8 = 2(y-8)
  And 8 years hence:-
  x+8 = (4/3)*(y+8)
  By solving the above two equations we get x=24 and y=16
  So Andromeda's present age is 24 years and in Binary it is 11000

• let achilles age 8 years ago b=x
  hence andromeds age is 2*x
  8 yrs hence achillis age is x+8+8=x+16
  and andromeds age becomes 2x+16
  2x+16=4/3(x+16)
  solving eq. we get x=8
  hence andromend age is 2*8+8
  24
  =11000
