profit percentage = profit / cost price
he has a profit of 4 pens so
4/20 * 100
=>20
therefore the profit % = 20%

pls explain
sorry i think its wrong
shall i explain the correct answer in this comment
let the cost of 1 pen = x then the cost of 20 pens will be 20x. yh
the cost of 20 pens is equal to the selling price of 16 pens. so. let the selling price of 1 pen be y. then the selling price of 16 pens = 16y. 20x = 16y. => x= 16/20 y
profit %, = profit / cost price. * 100. as profit = sp-cp. profit = 20y - 20x. => 20y-16y therefore it is 4y . profit % = 4y/16y * 100. => 25%.
sorry for the mistake . pls mark me as the brainliest
