Cannot be determinedExplanation
When Harris picks the wrong weight, he weighs 1100 grams but takes price of 1000 grams only. This is true in 3 cases out of 5. In remaining two cases, he weighs with accurate weight. ⇒ In 5 cases, quantity he weighs = (3 × 1100) + (2 × 1000) = 5300 grams In 5 cases, quantity for which he takes price = (5 × 1000) = 5000 grams He sells goods at cost price. Suppose cost price of 1 gram is T. ⇒ On selling 5300 grams, cost price for Harris = 5300T Selling price = Cost price of 5000 grams = 5000T We know, Selling Price = Cost Price × (1 - (Loss %)/100) ⇒ 5000T = 5300T × (1 - (Loss %)/100) ⇒ Loss percentageRelated questions
