Question

Roger made $25 profit on the stamp collection costing him $125. What was his profit as a percentage of the cost price?

Answer 1

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 = $20 \%$

Answer 2

STEP-BY-STEP SOLUTION:

Profit = $25

Cost = $125


Profit as a % of the cost price

= ( 25 / 125 ) × 100%

= ( 1 / 5 ) × 100%

= 20%

ANSWER: 20%
