b. Rs. 10
c. Rs. 45
d. Rs. 150

Answer:

First discount of 15% = 15% of 2000 = Rs. 300
After discount value = Rs. 2000 - Rs.300 = Rs. 1700

Second discount of 15% = 15% of Rs. 1700 =15x 1700 = Rs. 255
100
Difference = 600 - (300+255) = Rs. 45

100
∴ MP = Rs. 2000


8. While selling a jug online, the seller offered a discount of 23% but managed to make a profit of 10% which translates into Rs 77/-. What was the list price of the jug?

a. Rs. 770
b. Rs. 847
c. Rs. 1100
d. Rs. 1120

Answer:

Explanation:

List Price (LP) > Selling Price (SP) > Cost price (CP)
The seller manages to make 10% profit.
Value of this 10% profit = Rs. 77

% Profit =Profitx 100
Cost Price
∴ 10 =77x 100
CP
∴ CP = Rs. 770
And SP = 770+77 = Rs. 847
Price after Commission = Selling Price = (100-23)% of LP = 77% of LP
∴ 847 =77x LP
100
∴ LP = List Price = Rs. 1100


9. The cost of a watch is Rs. 900. To make the deal attractive to its customers, the shop sells it at a discount of 12% and still makes a profit of 10%. What is the advertised price?

a. Rs. 812.5
b. Rs. 1050
c. Rs. 1125
d. Rs. 1225

Answer:

Explanation:

Since profit of 10% is there, ∴ SP = (100+10)% of CP =110x 900 = Rs. 990
100
Discount = 12%
So, SP = (100-12)% of List Price
∴ 990 =88x LP
100
∴ LP = Rs. 1125
(List price = Advertised Price = Marked Price)


10. By what percentage should the cost price of an article be increased, so as to earn a profit of 20% even after allowing a discount of 40% on the price marked on the article?

a. 33.33%
b. 50%
c. 66.67%
d. 100%

Answer:

Explanation:

Discount = 40%
SP = (100-40)% of MP = 60% of MP
Profit = 20%
∴ SP = (100+20)% of CP
∴ 60% x MP = 120% of CP

∴ CP =1MP
2
∴ MP = 2CP
Since, MP should be twice of CP to fit into the criteria, we need to increase CP by 100% to make it MP.
