A seller charges 28% more from a customer as GST on an article. If customer paid Rs. 4544, what is the cost price of the article?

A Rs. 3550

B Rs. 2650

C Rs. 3840

D Rs. 2450

Correct Answer: Option A

Let the cost price of the article be 'P'

Then from given data,

\(\begin{array}{l}\mathrm P\;+\;\frac{28\mathrm P}{100}\;=\;4544\\=>\;128\mathrm P\;=\;454400\\=>\;\mathrm P\;=\;3550\end{array}\)

Hence, the cost price of the article = P = Rs. 3550
