A dishonest dealer sells the goods at 20\% loss on cost price but uses 15\% less weight. What is his percentage profit or loss?
(a)$5 \frac{11}{17} \%$ loss
(b)$5 \frac{15}{17} \%$ loss
(c)$5 \frac{15}{17} \%$ gain
(d)$5 \frac{11}{17} \%$ gain
Answer
Explanation
Gain/Loss\% $=\left\{\left(\frac{y-x}{100-y}\right) \times 100\right\} \%=\left\{\left(\frac{15-20}{100-15}\right) \times 100\right\} \%$ $$\begin{aligned} & =\left(\frac{-5}{85} \times 100\right) \%=-\frac{100}{17} \% \\ & =-5 \frac{15}{17} \% . \end{aligned}$$ Since it is -ve, hence it is a loss.
