Tanya's grandfather was 8 times older to her 16 years ago. He would be three times of her age 8 years from now. Eight years ago what was ratio of Tanyas age to her grandfather?

• 16 years ago, let T = x years and G = 8x years.
  After 8 years from now, T = (x+16+8) years and G = (8x+16+8) years.
  8x+24 = 3(x+24)
  5x =48
  8 years ago, T/G = x+8 / 8x + 8
  = (48/5 + 8) / (8*48/5+8) = 88/424 = 11/53.

• g-16=8(t-16)
  g+8=3(t+8)
  
  solving the two we get t/g=1/3..
