Let the cost price of a pen be x, then the cost price of a book is 2x And the Selling price of the pen and the book be a and b respectively Now according to the Question, Cost price of 20 pen = 20x and the profit = 6b Profit % = 6b/20x ×100 = 30b/x Similarly, Cost price of 20 books = 40x and the loss = 8a Loss % = 8a/40x × 100 = 20a/x Since the numerical values are equal ∴ 30b/x = 20a/x a/b = 3/2 The required ratio is 3:2
