    The diameter of the Moon is approximately one- fourth of that of the Earth .What is the (approx.) ratio of the volume of the Moon to that of Earth?

    A) 1/16

    B)  1/32  

    C)  1/48    

    D)  1/64

    Correct Answer: D

    Solution :

    Let x be the diameter of a Moon. Then,    \[\frac{\text{Volume}\,\,\text{of}\,\,\text{Moon}}{\text{Volume}\,\,\text{of}\,\,\text{Earth}}=\frac{\frac{4}{3}\pi {{\left( \frac{x}{8} \right)}^{3}}}{\frac{4}{3}\pi {{\left( \frac{x}{2} \right)}^{3}}}=\frac{1}{64}\]
