AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
\begin{aligned}
& {\text{Marked price of article }} \\
& = {\text{Rs}}{\text{. 500}} \\
& {\text{Selling price of article }} \\
& = {\text{90% }}\,{\text{of}}\,{\text{500}} \\
& = \frac{{90}}{{100}} \times 500{\text{ }} \\
& = {\text{Rs}}{\text{. 450}} \\
& {\text{Cost price of article }} \\
& = 450 \times \frac{{100}}{{120}}{\text{ }} \\
& = {\text{Rs}}{\text{. 375}} \\\end{aligned}
