Answer 2

If the shopkeeper sell the same dining table for price 12240, then its % gain will be 2%.

Step-by-step explanation:

If the cost price of the dining table is x, then the shopkeeper loses 15% by selling a dining table for selling it in the price of $x(1 - \frac{15}{100})  = 0.85x$.

Now, the selling price is given to be 0.85x = 10200

⇒ x = 12000

If the shopkeeper sell the same dining table for price 12240, then its % gain will be  

$\frac{12240 - 12000}{12000} \times 100$%

= 2% (Answer)
