Amount spent on Entertainment and Shopping
$$\eqalign{ & = \text{Rs.}\left(45800\times\frac{10+19}{100}\right) \cr & = \text{Rs.}\left(45800\times\frac{29}{100}\right) \cr & = \text{Rs. 13282}\cr} $$

(Amount spent on medicine) : (Amount spent on groceries)
$$\eqalign{ & = \left(45800\times\frac{11}{100}\right):\left(45800\times\frac{23}{100}\right) \cr & = 11:23 \cr} $$
