A product was offered at a 10% trade discount on the marked price. After a cash discount of 10%, the product was sold for ₹7,290. The marked price (in ₹) is:

To find the marked price of the product, we can trace the discounts applied step-by-step.

Let the marked price of the product be M.
First, a trade discount of 10% is offered on the marked price.
The price after the trade discount is:
$\mathrm{Price\; after\; trade\; discount}=M-0.10M=0.90M$

Next, a cash discount of 10% is applied to this new price.
The selling price (after both discounts) is:
$\mathrm{Selling\; Price}=0.90M-0.10\times \left(0.90M\right)$
$\mathrm{Selling\; Price}=0.90M\times (1-0.10)=0.90M\times 0.90=0.81M$

We are given that the product was sold for ₹7,290. Therefore:
$0.81M=7290$

Now, we solve for M:
$M=\frac{7290}{0.81}$
$M=\frac{729000}{81}$
Since $81\times 9=729$, we get:
$M=9000$

Thus, the marked price of the product is ₹9,000.
