A, B and C together start a business. Three times the investment of A equal four times the investment of B and the capital of B is twice that of C. The ratio of share of each in the profit ?

$$\eqalign{ & {\text{3A}} = {\text{4B}} \cr & {\text{B}} = {\text{2C}} \cr & \frac{{\text{A}}}{{\text{B}}} = \frac{4}{3} \cr & \frac{{\text{B}}}{{\text{C}}} = \frac{2}{1} \cr & {\text{A}}\,\,\,\,\,\,\,\,{\text{B}}\,\,\,\,\,\,\,\,{\text{C}} \cr & {\text{4}}\,\,\,\,\,\,\,\,\,\,{\text{3}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,{\text{2}}\,\,\,\,\,\,\,\,\,\,{\text{1}} \cr & \boxed{{\text{8}}\,\,:\,\,6\,\,\,:\,\,\,3\,} \cr} $$
