Question 87

On selling 56 chairs, Mohan earns proﬁt equal to the selling price of 6 chairs. What is the proﬁt percentage?

Solution

Let cost price of a chair = Rs. $$x$$ and selling price = Rs. $$y$$

Profit on selling 56 chairs = Rs. $$56(y-x)$$

According to ques,

=> $$56(y-x)=6y$$

=> $$56y-56x=6y$$

=> $$56x=56y-6y=50y$$

=> $$\frac{y}{x}=\frac{56}{50}$$

Let $$x=50$$ and $$y=56$$

Thus, profit % = $$\frac{(y-x)}{x}\times100$$

= $$\frac{(56-50)}{50}\times100$$

= $$6\times2=12\%$$

=> Ans - (C)
