Dupe bought a book for 25k, and sold it to yemi for 30k. Find Dupe's percentage profit

To find Dupe's percentage profit, we need to calculate the profit first.

Profit = Selling Price - Cost Price

Dupe's selling price is 30k, and the cost price is 25k.

Profit = 30k - 25k = 5k

Now, let's calculate the percentage profit.

Percentage Profit = (Profit / Cost Price) * 100

Percentage Profit = (5k / 25k) * 100 = 20%

Therefore, Dupe's percentage profit is 20%.
