In a shop, 80\% of the articles are sold at a profit of 10\% and the remaining at a loss of 40\%. What is the overall profit/loss?
(a)10\% profit
(b)10\% loss
(c)5\% loss
(d)No profit no loss
Answer
Answer (as printed): D
Explanation
Let the total C.P. of all the articles be ₹ $x$. Then, C.P. of $80 \%$ of the articles $=80 \%$ of $₹ x=₹ \frac{4 x}{5}$. C.P. of the remaining articles $=₹\left(x-\frac{4 x}{5}\right)=₹ \frac{x}{5}$. TotalS.P. $=₹\left(110 \%\right.$ of $\frac{4 x}{5}+60 \%$ of $\left.\frac{x}{5}\right)=₹\left(\frac{22 x}{25}+\frac{3 x}{25}\right)=₹ x$. Since C.P. = S.P., there is no profit, no loss.
