a. Rs. 0
b. Rs. 10
c. Rs. 45

Difference = 600 - (300+255) = Rs. 45
7. A man wanted to sell his bat at 5% discount. His brother who was a cricketer wanted to buy that bat so the man sells it at 8% discount. In this deal, the man makes Rs 60/- less in profit. How much was the marked price of the bat?

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
∴ CP = Rs. 770
And SP = 770+77 = Rs. 847
Price after Commission = Selling Price = (100-23)% of LP = 77% of LP
∴ 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
Discount = 12%
So, SP = (100-12)% of List Price
∴ 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%
∴ 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.
a. Rs. 0
b. Rs. 10
c. Rs. 45
d. Rs. 150
Answer:
Explanation:
30% discount = 30% of 2000 = Rs. 600
Now, if you offer two successive discount of 15% each, it works out to
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 = | 15 | x 1700 = Rs. 255 |
| 100 |
7. A man wanted to sell his bat at 5% discount. His brother who was a cricketer wanted to buy that bat so the man sells it at 8% discount. In this deal, the man makes Rs 60/- less in profit. How much was the marked price of the bat?
a. Rs. 1800
b. Rs. 2000
c. Rs. 6000
d. Rs. 9000
Answer:
Explanation:
Difference in discount = 8% - 5% = 3%
Due to this 3% man makes Rs. 60 less in profit
That means 3% of Marked Price = 60
| ∴ | 3 | x MP = 60 |
| 100 |
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 = | Profit | x 100 |
| Cost Price |
| ∴ 10 = | 77 | x 100 |
| CP |
And SP = 770+77 = Rs. 847
Price after Commission = Selling Price = (100-23)% of LP = 77% of LP
| ∴ 847 = | 77 | x LP |
| 100 |
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 = | 110 | x 900 = Rs. 990 |
| 100 |
So, SP = (100-12)% of List Price
| ∴ 990 = | 88 | x LP |
| 100 |
(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 = | 1 | MP |
| 2 |
Since, MP should be twice of CP to fit into the criteria, we need to increase CP by 100% to make it MP.
