- 8722
- 7892
- 8712
- 8840
Correct Option: C
Price after 10% discount = 10000 - 10 % of 10000 = 10000 - 0.1 x 10000 = 9000
Price after another 20% discount = 9000 - 20 % of 9000 = 7200
Price after 10% of transportation charges = 7200 + 7200 x 0.1 = 7920
Price after 10% of profit = 7920 + 7920 x 0.1 = 8712
∴ Selling price = 8712
