The price of an article is fixed at a certain percent above the cost price and sold it at 5% discount. If the cost price of the
article is Rs 16,000 and sold for Rs 20,900 with 10% VAT,
by how many percent is the marked price above the cost
price?​

24.1%

Step-by-step explanation:

The selling price includes a VAT (which is a form of tax) and a discount.

A Vat is a form of tax which increases the price of a good and a discount reduces the price.

The vat increases price by 10% and the tax reduces the price by 5%.

So the original selling price before all these adjustments would be

20,900 x ( 1 -0.1  + 0.05)

20,900 x 0.95 = 19855

Mark up = (selling price - cost price) / cost price

(19855 - 16,000) / 16,000 = 0.241 = 24.1%
