1. Discount is always calculated on which price?

2. A watch marked Rs 1600 is sold for Rs 1360 after discount. The discount percent is:
Show answer
Answer: A) 15%
Discount = 1600 - 1360 = 240. Discount% = x 100 = 15%.
3. A TV is marked at Rs 25000. A discount of 8% is given and then 18% GST is charged on the discounted price. What is the final amount paid?
Show answer
Answer: B) 27140
Discount = 8% of 25000 = 2000, so price = 23000. GST = 18% of 23000 = 4140. Final = 23000 + 4140 = Rs 27140.
4. A restaurant bill before tax is Rs 1500.
GST is split as 9% CGST and 9% SGST.
What is the total bill including both taxes?
Show answer
Answer: C) 1770
Total GST = 9% + 9% = 18% of 1500 = 270. Total bill = 1500 + 270 = Rs 1770.
5. A shopkeeper marks his goods 25% above cost and earns a profit of 10% after allowing a discount.
What is the rate of discount he gives?
(Hint: take cost price as Rs 100.)
Show answer
Answer: A) 12%
Take CP = 100. MP = 125. SP for 10% profit = 110. Discount = 125 - 110 = 15 on 125 = x 100 = 12%.
