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

STEP-BY-STEP SOLUTION:

Profit = $25

Cost = $125


Profit as a % of the cost price

= ( 25 / 125 ) × 100%

= ( 1 / 5 ) × 100%

= 20%

ANSWER: 20%

Answer 2

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 }} * 100`

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

Profit percentage
`=(25)/(125) * 100\Rightarrow (1)/(5) * 100\Rightarrow (100)/(5)\%\Rightarrow 20\%`

Therefore, Profit percentage =
`20 \%`
