The profit percentage gained by roger is $20 \%$

SOLUTION:

Given that, Roger made $\$25$ profit on the stamp collection costing him $\$125$ . We have to find his profit as a percentage of the cost price

Profit percentage is profit gained divided by the cost price multiplied by 100.

Therefore, Profit percentage on stamp collection $=\frac{\text { profit gained }}{\text { cost price }} \times 100$

Here, profit gained = $\$25$ and cost price = $\$125$

Profit percentage $=\frac{25}{125} \times 100\Rightarrow \frac{1}{5} \times 100\Rightarrow \frac{100}{5}\%\Rightarrow 20\%$

Therefore, Profit percentage = $20 \%$
