To determine the optimal consumption of goods X and Y, we can use the concept of the marginal utility per rupee spent. The marginal utility per rupee spent is calculated by dividing the marginal utility of a good by its price.

$\text{Marginal Utility per Rupee}=\genfrac{}{}{0ex}{}{\text{Marginal Utility}}{\text{Price}}$

For good X: $\text{Marginal Utility per Rupee for X}=\genfrac{}{}{0ex}{}{30}{3}=10$

For good Y: $\text{Marginal Utility per Rupee for Y}=\genfrac{}{}{0ex}{}{45}{5}=9$

Savita will allocate her budget in such a way that the marginal utility per rupee is the same for both goods. Since the marginal utility per rupee for good X is higher (10 > 9), Savita will allocate more of her budget to good X.

Therefore, the correct option is: More of good X
