1. The marked price on an item was Rs 2000/- but the shopkeeper offered a double discount of 20% and 15%. How much did he finally sell the item for?

a. Rs. 640
b. Rs. 1300
c. Rs. 1360
d. Rs. 1600

Explanation:

First discount = 20%
∴ Price after First discount = 100-20% = 80% of M.P = 80% * 2000 = Rs. 1600
Second discount = 15%
∴ Price after Second discount = 100-15% = 85% of new price = 85% of 1600 = Rs. 1360/-
So, the item was finally sold for Rs. 1360/-

2. One shopkeeper keeper was offering two successive discounts of 15% and 10% on an item while the second one is offering flat 25% discount on the same item. Which shopkeeper should I buy the item from?

a. First Shopkeeper
b. Second Shopkeeper
c. Any of them; both are same
d. Data Insufficient

Explanation:

Tip:
 Single equivalent of 2 discounts = ADD - MULTIPLY 100

ADD = 15 + 10 = 25
 MULTIPLY = 15 x 10 = 1.5 100 100
∴ Single equivalent = 25 - 1.5 = 23.5%
The single equivalent discount offered by first shopkeeper is 23.5%.
Second shopkeeper is offering it at 25%, which makes the item cheaper for the buyer.

3. Find the single equivalent discount of 10%, 15% and 20%.

a. 38.8%
b. 45%
c. 61.2%
d. None of the above

Explanation:

Approach 1:

Take Value = 100
For 1st discount of 10%, 1st value = (100-10)% of 100 = 90% of 100 = 90
For 2nd discount of 15%, 2nd value = (100-15)% of 90 = 85% of 90 = 76.5

 For 3rd discount of 20%, Final value = (100-20)% of 76.5 = 80 x 76.5 = 61.2 100
So, Discount = 100 - 61.2 = 100 - 61.2 = 38.8%

Approach 2:

Tip:
Single equivalent of 3 discounts = (1 - MULTIPLY) x 100

 100 - 10% = 90% = 90 ; 100 - 15% = 85% = 85 ; 100 100
 100 - 20% = 80% = 80 100
 MULTIPLY = 90% x 85% x 80% = 90 x 85 x 80 100 100 100
 ∴ (1-MULTIPLY) x 100 = ( 1 - 90 x 85 x 80 ) x 100 = 38.8% = Single equivalent 100 100 100

4. The cost price of the goods for a shopkeeper was X. He marked them at a 20% higher price than the Cost Price. Finally he sold the goods at 30% discount. Did he earn a profit or incur a loss? How much?

a. 5% Profit
b. 5.5% Profit
c. 10% Loss
d. 16% Loss

Explanation:

Let CP = Rs. 100
Marked Price = 20% more than CP
∴ MP = Rs. 120
Discount = 30% on marked price
∴ SP = (100-30)% of MP

 ∴ SP = 70 x 120 = Rs. 84 100
 Loss% = 100-84 x 100 = 16% 100

5. The marked price of a chair was Rs 12,800/-. The shopkeeper was offering it for a discount of 20% but on further bargaining agreed to offer a successive discount and finally sold the chair for Rs 9,216/- What was the second discount offered by him?

a. 5%
b. 10%
c. 20%
d. 25%
