Let the marked price of the item be P.
Given that a selling price of Rs. 276 results in a discount of 8%, we can write:
P - (8/100) x P = 276
0.92P = 276
P = 276 / 0.92
P = 300
Now, we need to find the selling price with a 13% discount:
Selling price = P - (13/100) xP
Selling price = 300 - (13/100)*300
Selling price = 300 - 39
Selling price = Rs. 261
Therefore, the item should be sold at Rs. 261 to offer a discount of 13%.
