Question

1.If a shopkeeper bought 30 meters of cloth at a particular price. Again, he sold
20 meters of cloth at that particular price. What is the percentage of profit of
the shopkeeper?​

Answer 1

Answer:

50

Step-by-step explanation:

let the cost price of 1m cloth = x

the cost price of 30m cloth = 30x

let selling price of 1m cloth = y

the selling price of 20 m cloth = 20y

according to the question

20y = 30x

y = 1.5x

profit per meter = selling price - cost price    {per meter}

profit = y - x

profit = 1.5x - x

profit = 0.5x

profit percentage = (profit / cost price) x 100

profit percentage = (0.5x / x) *100

profit percentage = 50 percent
