# 3.A shopkeeper buys 80 articles for ₹ 2,400 and sells them for a profit of 16%. Find the selling price of one article.

We have Cost price of 80 articles = ₹ 2,400
So, Cost of 1 article = ₹ $$\frac { 2400 }{ 80 } = ₹ 30$$

Given Profit = 16%

So, we know $$SP =CP \times (1+\frac{profit}{100})$$

$$\qquad =30 \times (1+\frac{16}{100})$$

$$\qquad =30 \times (\frac{116}{100})=₹ 34.80$$

Hence, the selling price of one article =₹ 34.80
