A shopkeeper claims to sell 22% of his items on the loss, but he weighs 30% less weight. Find the actual loss or profit percentage? एक दुकानदार अपने वस्तुओ को 22% हानि पर बेचने का दावा करता है परन्तु वह 30% कम वजन तौलता है| वास्तविक हानि या लाभ प्रतिशत ज्ञात कीजिये?

The shopkeeper claims 22% loss, so selling price = 78% of cost price. But he weighs 30% less, meaning he gives only 70 units but charges for 100 units. So his actual cost is for 70 units, but he receives payment for 100 units at 78% of marked price. Effective cost = 70, effective selling = 78. Profit = 78 - 70 = 8. Profit% = 8/70 × 100 = 11.42%.
