C. 6 : 5 : 10
D. 10 : 5 : 6
Answer: Option B
Solution(By Examveda Team)
Let their initial investments be x, 3x and 5x respectivelyThen,
$$ = {\text{A}}:{\text{B}}:{\text{C}}$$
$$ = \left( {x \times 4 + 2x \times 8} \right)$$ : $$\left( {3x \times 4 + \frac{{3x}}{2} \times 8} \right)$$ : $$\left( {5x \times 4 + \frac{{5x}}{2} \times 8} \right)$$
$$\eqalign{ & = 20x:24x:40x \cr & = 5:6:10 \cr} $$
