Question: Mr. Grey's house was worth $100,000. He sold the house to Mr. Brown at a profit of 10%. After one year, Mr. Brown sold the house to his other friend with a 10% loss. How much was Mr. Brown's selling price?
Answer:
Mr. Grey had a $100 000 x 10 / 100 = $10,000 profit. So, Mr. Grey sold the house to Mr. Brown for $100 000 + $10 000 = $110,000. Mr. Brown sold the house $110 000 x 10 / 100 = $11,000 less than its purchased price. Thus, Mr. Brown sold it for $110 000 - $11 000 = $99,000 to his friend. The answer is 99000.
