At 10% discount the selling price of an article is Rs 4500, what is the selling price (in Rs) if the discount is 27.5%?
$$\frac{100-10}{100} \times CP = 4500$$
$$\frac{90}{100} \times CP = 4500$$
$$CP = 5000$$
if 27.5% discount is allowed then,
$$SP = \frac{100-27.5}{100} \times 5000$$
$$SP = \frac{72.5}{100} \times 5000$$
$$SP = 3625$$
so the answer is option B.
