Question

A shopkeeper professes to sell his goods at the cost price, but due to a defect in weighing machine it
shows 100 grams less than the original weight, besides he offers 10% extra grams per kg. A customer
goes and buys one kg sugar. Now what is the profit or loss incurred by the shopkeeper (include offer
of 10 %)?​

Answer 1

GIVEN:

decrease in weight due to defect=100gm

extra discount=10%

ANSWER:

amount of sugar Customer buys=1000gm

weight after decrease=900gm

10%of 1000gm=100gm

Now add this 100gm in 900gm

weight after extra discount =1000gm or 1kg

So to the shopkeeper there is NO LOSS NO PROFIT
