(e)73 \%
Answer
Explanation
Total expenditure in 2007 $$\begin{aligned} & =₹(288+98+3.00+23.4+83) \text { lakh } \\ & =₹ 495.4 \text { lakh } \end{aligned}$$ Total expenditure in 2011 $$\begin{aligned} & =₹(420+142+3.96+49.4+98) \text { lakh } \\ & =₹ 713.36 \text { lakh. } \end{aligned}$$ Let $495.4=x \%$ of ₹ 713.36. Then, $$\frac{x}{100} \times 713.36=495.4 \Rightarrow x=\left(\frac{495.40}{713.36} \times 100\right)=\left(\frac{12385}{17834} \times 100\right)=69.4 \% \simeq 69 \% .$$
