Example:   The marked price of a shirt is Rs.1000. A shopkeeper offers 10% discount on this shirt. How much will you have to pay, finally?

Solution :   Discount =10% of 1000 = \frac{10}{100} × 1000 =Rs 100

Selling Price = 1000 – 100 = Rs 900

  • But in exam,you can do it directly in your head.So just think that 10 percent discount means you’ve to pay 100 percent minus 10 percent=90 percent of the marked price which means, ( \frac{90}{100}) 1000 =Rs. 900

Question 1.  The successive discount of 30% and 40% is given on holiday package. If the price of the package is 10000. What is final price of the package? 

Options

 A. 2100 

B. 4200

C. 2400

D. 5800

Solution:     Total discount = x + y – \frac{xy}{100}

Total discount = 30 + 40 – \frac{30 × 40}{100}

Total discount = 58% 

Discount = 58% of 10000 

Discount = 5800 

S.P = M.P – Discount  

S.P = 10000 – 5800 

S.P = 4200 

Correct option: B

Question 1.  In a shop a dress was on a discount. The discount on the printed price of the dress are 20% and 12% and 5 % respectively, what is the total percentage of actual discount given on the dress? 

Options

A. 33.12% 

B. 33.5%

C. 21.3%

D. 33%

Solution:     Total discount = x + y – \frac{xy}{100}

                     First, calculate for first 2 discounts = 20 + 12 –  \frac{20 × 12}{100} = 29.6% 

Now discount D = 29.6% and Z = 5 % 

Total discount = D + Z – \frac{DZ}{100}

Total discount = [29.6 + 5 – \frac{29.6  ×5}{100}] % 

Total discount = 33.12% 

Therefore total discount is 33.12% 

Correct option: A

Question 2. In a shop a dress was on a discounts. The discount on the printed price of the dress are 5% and 10% and 15 % respectively. The marked price of the dress is 1500. Then calculate overall discount and selling price of the dress?

B. 1900.125

C. 1910.125

D. 1090.125

Solution:     Total discount = x + y – \frac{xy}{100}

                     First, calculate for first 2 discounts = 5 + 10 – \frac{5 × 10}{100} = 14.5% 

Now discount D = 14.5% and Z = 15 % 

Total discount = D + Z – \frac{DZ}{100}

Total discount = [14.515 – \frac{14.5 × 15}{100}] % 

Total discount = 27.32% 

Discount = 27.32% of 1500 = 409.875 

Selling price = 1500 – 409.875 = 1090.125 

Correct option: D

Options

A. 327600 

B. 376200

C. 372600

D. 372060

Solution:     Selling price = price – discounts 

Selling price = 500000 x (1- \frac{20}{100}) x (1- \frac{10}{100}) x (1- \frac{10}{100}) 

Selling price = 324000 

Rate of sales tax = 15% 

Price to be paid by buyer = Selling price + tax 

Price to be paid by buyer = 324000 + 15% of 324000 

Price to be paid by buyer = 324000 + 48600 

Price to be paid by buyer = 372600
