A merchant professes to lose 4\% on a certain tea but he uses a weight equal to 840g instead of 1 kg. Find his real loss or gain percent.
(a)$14 \frac{2}{7} \%$ loss
(b)$14 \frac{2}{7} \%$ gain
(c)$16 \frac{2}{7} \%$ loss
(d)$16 \frac{2}{7} \%$ gain
Answer
Explanation
Percentage deduction in weight $=\left(\frac{160}{1000} \times 100\right) \%=16 \%$. $$\begin{aligned} \therefore \text { Gain } / \text { Loss } \% & =\left[\left(\frac{y-x}{100-y}\right) \times 100\right] \%=\left(\frac{16-4}{100-16} \times 100\right) \% \\ & =\left(\frac{12}{84} \times 100\right) \%=\frac{100}{7} \%=14 \frac{2}{7} \% . \end{aligned}$$ Since it is +ve, hence it is a gain.
