Given:
Market price = ₹2300
Discount percentage = 20%
\(Discount = Market\, Price\) \(\times\) \((\frac{Discount\, Rate}{100})\)
\(Discount = 2300 \times (\frac{20}{100})\)
= 2300 x 0.20
= ₹ 460
Selling Price = Market Price - Discount
= 2300 - 460
= ₹1840
So, the final discount is ₹460, and the selling price is ₹1840.
