Answer:
20%
Step-by-step explanation:
The selling price before VAT is added was ...
(Rs 5424)/(1 +13%) = Rs (5424/1.13) = Rs 4800
The profit is the difference between this price and the cost:
profit = Rs 4800 -4000 = Rs 800
So, the profit percentage is ...
profit / cost × 100% = (800/4000)×100% = 20%
The seller made a profit of 20% on the article.
