Calculating Marked Price After Commission Deduction

Let the Marked Price (MP) of the T.V. set be MP.

A commission of 10% is deducted from the marked price. This means the selling price (SP) is 10% less than the marked price.

Commission Amount = $10\%$ of MP = $0.10 \times \text{MP}$

The cost after deducting the commission (Selling Price) is given as ₹9,090.

Selling Price = Marked Price - Commission Amount

₹9,090 = MP - $(0.10 \times \text{MP})$

₹9,090 = MP $(1 - 0.10)$

₹9,090 = $0.90 \times \text{MP}$

Finding the Marked Price

To find the marked price (MP), we rearrange the equation:

MP = $\frac{₹9,090}{0.90}$

MP = $₹\frac{90900}{90}$

MP = ₹10,100

Therefore, the marked price of the T.V. set is ₹10,100.00.
