Tick (✓) the correct answer

The selling price of an article is $\frac{6}{5}$ of the cost price. The gain per cent is

(a) 20%

(b) 25%

(c) 30%

(d) 120%


(a) 20%

Let Rs $x$ be the CP of each article.

SP of an article $=$ Rs $\frac{6}{5} \mathrm{x}$

Now, gain $=(\mathrm{SP}-\mathrm{CP})$

$=\operatorname{Rs}\left(\frac{6}{5} x-x\right)$

$=\operatorname{Rs} \frac{x}{5}$

$\therefore$ Gain percentage $=\left(\frac{\text { gain }}{\mathrm{CP}} \times 100\right) \%$

$=\left(\frac{\frac{x}{5}}{x} \times 100\right) \%$

$=\left(\left(\frac{x}{5} \times \frac{1}{x}\right) \times 100\right) \%$

$=20 \%$
