What is the ratio of the amount spent by the family on medicine to the amount spent on groceries?

Answer: Option D

Percentage Break-up of expenditure is:
$$\begin{array}{rl}& \text{Investments →}\left(\frac{54}{360}\times 100\right)\%\\ & =15\%\\ & \text{Commuting →}\left(\frac{79.2}{360}\times 100\right)\%\\ & =22\%\\ & \text{Shopping →}\left(\frac{68.4}{360}\times 100\right)\%\\ & =19\%\\ & \text{Groceries →}\left(\frac{82.8}{360}\times 100\right)\%\\ & =23\%\\ & \text{Medicines →}\left(\frac{39.6}{360}\times 100\right)\%\\ & =11\%\\ & \text{Entertainment →}\left(\frac{36}{360}\times 100\right)\%\\ & =10\%\end{array}$$

(Amount spent on medicine) : (Amount spent on groceries)
$$\begin{array}{rl}& =\left(45800\times \frac{11}{100}\right):\left(45800\times \frac{23}{100}\right)\\ & =11:23\end{array}$$
