Question
A dishonest dealer announces selling his articles with
22% loss, but uses 35% lighter weights. What is the percentage of his profit or loss?Solution
Let the CP =100. Dealer announces 22% loss which implies- Selling Price =100× (100-22)/100 SP=78 Now – However, the dealer uses weights that are 35% lighter. This means that for every unit weight he claims to sell, he sells only 65% of that weight. Effective CP =100×65/100 E. CP=65. Profit =SP-CP P=78-65=13. Profit percentage = (P/E.CP) ×100 =13/65 ×100 =20%
