A washing machine marked at ₹28,000 is sold at two successive discounts of 15% and 10%. An additional discount of 5% is offered for cash payment. The selling price of the washing machine at cash payment is:

₹20,349

Marked price of the washing machine = 28,000 

Three discounts = 15% , 10% and a additional discount of 5% is given

Selling price = 28,000 × \(\frac{17}{20}\) × \(\frac{9}{10}\) × \(\frac{19}{20}\) = ₹20,349
