    A)  1: 2                 

    B)  1 : 5

    C)  3: 8                 

    D)  None of these

    Correct Answer: D

    Solution :

    [d] 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. \[\therefore 8x+24=3\,\,(3+24)\Rightarrow 5x=48\] 8 years ago, \[\frac{T}{G}=\frac{x+8}{8x+8}=\frac{\frac{48}{5}+8}{8\times \frac{48}{5}+8}=\frac{88}{424}=\frac{11}{53}\]
