A shopkeeper buys potatoes at $1.40 per kilogram and sells them for $1.80 per kilogram. What is his percentage profit?
28.6%
25%
30%
32%
Explanation
Percentage profit is calculated as (Profit / Cost Price) * 100. Profit is $1.80 - $1.40 = $0.40. Therefore, percentage profit = ($0.40 / $1.40) * 100 = 28.6% (to 1 decimal place).
