Question 56

The profit on selling 35 mangoes is equal to the cost price of 7 mangoes. What is the profit percentage?

Solution

Let cost price of 1 mango = Rs. $$x$$ and selling price = Rs. $$y$$

=> Profit on selling 35 mangoes = Rs. $$35(y-x)$$

According to ques,

=> $$35(y-x)=7x$$

=> $$35y=7x+35x=42x$$

=> $$\frac{x}{y}=\frac{35}{42}=\frac{5}{6}$$

Let $$x=5$$ and $$y=6$$

$$\therefore$$ Profit % = $$\frac{(y-x)}{x}\times100$$

= $$\frac{6-5}{5}\times100=20\%$$

=> Ans - (B)
