Consider a grid where Cynthia and David compute sums along each row and column respectively. The grid has 30 rows and 50 columns. Cynthia adds up the numbers of each row, averaging these 30 sums to get a value $C$. Conversely, David sums each column's number, producing an average of these sums noted as $D$. Calculate the value of $\frac{C}{D}$.
A) $\frac{3}{5}$  
B) $\frac{2}{3}$   
C) $\frac{3}{2}$   
D) $\frac{5}{3}$   
E) $\frac{4}{3}$
