Answer
Answer (as printed): C
Explanation
Let the total expenditure be ₹ $x$ crores. Then, $17.5 \%$ of $x=2.45$ $$\Rightarrow \frac{17.5 x}{100}=2.45 \Rightarrow x=\frac{2.45 \times 100}{17.5}=\frac{2450}{175} \Rightarrow x=14 .$$ ∴ Total expenditure $=₹ 14$ crores. Expenditure on Advertisement, Taxes, Research and Development $$\begin{aligned} & =[(15+10+5) \% \text { of ₹ } 14 \text { crores }] \\ & =₹\left(\frac{30}{100} \times 14\right) \text { crores } \\ & =₹ 4.2 \text { crores. } \end{aligned}$$
