Cost price of one book (copy) = P
Sale price = SP
Amount earned by selling 20 copies = 20 * SP
Profit earned = 1 *SP
Cost price for 20 copies = 20 * SP - SP = 19 * SP
Profit % = 1*SP/(19*SP) * 100 = 5.26 %
Sale price = SP
Amount earned by selling 20 copies = 20 * SP
Profit earned = 1 *SP
Cost price for 20 copies = 20 * SP - SP = 19 * SP
Profit % = 1*SP/(19*SP) * 100 = 5.26 %
