                A shopkeeper buys 80 articles for Rs 2,400 and sells them for a profit of 16%. Find the selling prince of one article.

Answer:

                CP of 80 articles = Rs 2400 Profit = 16% of Rs 2400 \[=\text{Rs}\,\frac{16}{100}\,\times 2400\] = Rs 384 \[\therefore \] SP of 80 articles = CP + Profit = Rs 2400 + Rs 384 = Rs 2784 \[\therefore \] SP of 1 article = Rs \[=\frac{2784}{80}\]  = Rs 34.80 Hence, the selling price of one article is Rs 34.80.
