What is statement

To find the price at which the shopkeeper would have sold the article to gain a 10% profit, we need to understand how the price is affected by a loss of 10%.

Let's assume the original price of the article, before any loss or gain, is denoted by 'x'.

When the shopkeeper sells the article for Rs. 1200, he incurs a loss of 10%. We can calculate this loss by multiplying the original price 'x' by 10% (or 0.10), and subtracting it from the original price 'x'.

Loss = x * 0.10
Selling price = x - Loss

According to the given information, the selling price is Rs. 1200. So we can set up the equation:

x - (x * 0.10) = 1200

Now we can solve for 'x' to determine the original price, which represents the cost price for the shopkeeper.

x - 0.10x = 1200
0.90x = 1200
x = 1200 / 0.90
x ≈ 1333.33

So, the original price (cost price) of the article is approximately Rs. 1333.33.

To calculate the selling price that would give the shopkeeper a 10% profit, we need to add 10% (or 0.10) of the cost price to the cost price.

Profit = x * 0.10
Selling price = x + Profit

Let's calculate the selling price:

Selling price = 1333.33 + (1333.33 * 0.10)
Selling price ≈ 1333.33 + 133.33
Selling price ≈ 1466.66

Therefore, to gain a 10% profit, the shopkeeper would have to sell the article for approximately Rs. 1466.66.
