Tick (✓) the correct answer:

On selling 100 pencils a man gains the selling price of 20 pencils. His gain per cent is

(a) 20%

(b) 25%

(c) $22 \frac{1}{2} \%$

(d) $16 \frac{2}{3} \%$



(b) 25%

Let the SP of 100 pens be Rs $x$.

SP of 1 pen $=$ Rs $\frac{x}{100}$

Profit $=$ Rs $\frac{20 x}{100}$

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

Now, $\mathrm{CP}=x-\frac{x}{5}$

$=\frac{4 x}{5}$

$\therefore$ Gain percentage $=\frac{\frac{x}{5}}{\frac{5 x}{5}} \times 100$

= 25%
