(1) A pair of shoes costs $200.A shopkeeper sells it at a loss of $10. (a) Find the selling price and the loss percentage of the shoes. The selling price = $200 - $10 = $190 The loss percentage of the shoes = loss/cost x 100% = $10/$200 x 100% = 5% (b) If the shop marks the pair of shoes at $250,what discount percentage will be given to the customer? ($250 - $190)/$250 x 100% = 24% discount (2) Paul bought a electronic game at $750 and sold it to John at a profit of 20%.Later, John sold the game to George. (a) How much did John pay to Paul? John paid to Paul 120% of $750 = $750 x 1.2 = $900 (b) If George paid $60 more than Paul, what is the profit/loss percentage of John? George paid John = $750 + $60 = $810 John lost $900 - $810 = $90 The loss percentage of John = $90/$900 x 100% = 10% 1. A number is increased by 20% and the result is 48. The number x 120/100 = 48 the number = 48/1.2 = 40 2. If A is 10% greater than B and A = 110, (110 – B)/B = 10/100 110– B = 0.1B 110 = 1.1B B = 100
