A) 4: 25
B) 2: 75
C) 2: 15
D) 4: 15
Correct Answer: A
Solution :
\[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{S_{1}^{3}}{S_{2}^{3}}=\frac{8}{125}\Rightarrow \frac{{{S}_{1}}}{{{S}_{2}}}=\frac{2}{5}\] Now, \[\frac{{{A}_{1}}}{{{A}_{2}}}=\frac{6\times S_{1}^{2}}{6\times S_{1}^{2}}=\frac{6}{6}\times {{\left( \frac{2}{5} \right)}^{2}}=\frac{4}{25}\]\[\Rightarrow {{A}_{1}}:{{A}_{2}}=\]
