Given data:

A dishonest merchant makes a 10% profit at the time of buying and a 5% loss at the time of selling the goods he trades.

By doing so, he made a profit of Rs. 900 on a particular item.

To find: the real cost price of the item sold

Step-by-step explanation:

Let the real cost of the item was Rs. x

Then the merchant bought the item at

Rs. x (1 - 10/100)

= Rs. x × 90/100

= Rs. 9x/10

He sold the item at a loss of 5%

Thus selling price of the item was

Rs. 9x/100 (1 - 5/100)

= Rs. 9x/10 × 95/100

= Rs. 171x/200

Given, he made a profit of Rs. 900 on that item.

Then, 9x/10 - 171x/200 = 900

⇨ (9x × 20 - 171x)/200 = 900

⇨ 180x - 171x = 900 × 200

⇨ 9x = 180000

x = 20000

Answer: The real cost price of the item sold was Rs. 20000
