A person bought an article at 30% discount on its marked price. The person then sold it at 30% profit for ₹427.70. What was the marked price of the article?

₹470

Let MP =  m

CP = m × \(\frac{70}{100}\)

According to the question

m × \(\frac{70}{100}\) × \(\frac{130}{100}\) = 427.70

m = 427.70 × \(\frac{100}{130}\) × \(\frac{100}{70}\)

m = 470
