Question
A dishonest dealer announces selling his articles with a
25% loss but uses 40% lighter weights. What is the percentage of his profit or loss?Solution
Let the CP =100. Dealer announces 25% loss which implies- Selling Price =100× (100-25)/100 SP=75 Now – However, the dealer uses weights that are 40% lighter. This means that for every unit weight he claims to sell, he sells only 60% of that weight. Effective CP =100×60/100 E. CP=60. Profit =SP-CP P=75-60=15. Profit percentage = (P/E.CP) ×100 =15/60 ×100 =25%
