    D) \[33\frac{1}{3}%\]

    Correct Answer: B

    Solution :

    Let percentage expenditure on electricity bill is x% of another expenditure. So, \[\left( 30+25+\frac{90}{360}\times 100 \right)\times x%\] \[\left( \frac{72}{360}\times 100 \right)(55+25)x%=\frac{72}{360}\] \[x=\frac{72}{360}\times \frac{100}{80}\times 100\Rightarrow \]25%
