Question

a trader sold 80 sharpener and earned a profit equal to the selling price of 24 sharpeners find the profit9ò​

Answer 1

Let selling price(sp) of 1 sharpner be y

Cost price(cp) of 80 sharpners = 80y - 24y = 56y

[(sp - cp)/cp] × 100 = profit

so, [(80y - 56 y)/ 56y] × 100 = profit

[24y/56y] × 100 = profit

(0.428) × 100 = profit

42.8 % = profit

So, profit is 42.8 %
