A. 2 : 3
B. 3 : 2
C. 3 : 4
D. 4 : 3
Answer: Option C
Solution(By Examveda Team)
Let their radii be 3x, 4x and heights be 4y, 3yRatio of their volumes :
$$\eqalign{ & = \frac{{\pi \times {{\left( {3x} \right)}^2} \times 4y}}{{\pi \times {{\left( {4x} \right)}^2} \times 3y}} \cr & = \frac{{36}}{{48}} \cr & = \frac{3}{4}\,Or\,3:4 \cr} $$
