A) 1 : 2
B) 1 : 5
C) 3 : 8
D) 11 : 53
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. \[\therefore \] \[8x+24=3(x+24)\Leftrightarrow 5x=48.\] 8 years ago, \[\frac{T}{G}=\frac{x+8}{8x+8}=\frac{\frac{48}{5}+8}{8\times \frac{48}{5}+8}=\frac{88}{424}=\frac{11}{53}\]You need to login to perform this action.
