    The ratio of the volumes of two cones is 2 : 3 and the ratio of radii of their bases is 1 : 2. The ratio of their heights is

    A) 3 : 8     

    B)  8 : 3

    C)  4 : 3    

    D)  3 : 4

    Correct Answer: B

    Solution :

    According to the question, \[\frac{{{r}^{2}}\times {{h}_{1}}}{4{{r}^{2}}\times {{h}_{2}}}=\frac{2}{3}\] \[\Rightarrow \]\[\frac{{{h}_{1}}}{{{h}_{2}}}=\frac{2}{3}\times \frac{4}{1}=\frac{8}{3}=8:3\]
