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
Answer: c. Rs. 1360
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
Answer: b. Second Shopkeeper
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
Answer: a. 38.8%
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% =

∴ (1-MULTIPLY) x 100 = ( 1 -

) x 100 = 38.8% = Single equivalent

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
Answer: 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%

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%
Answer: b. 10%
Explanation:
Price after 1st discount of 20% = (100-20)% = 80% of Marked Price
∴ Price =
80
x 12800 = Rs. 10,240
100
SP = (100-Discount) % of Price
∴ 9216 = (100-Discount) % x 10240
∴
100-Discount
=
9216
-----------> Converting discount percent to normal fraction
100
10240
∴ Discount = 10% = This is the percent of 2nd discount offered.
