A. 22%
B. 25%
C. 28%
D. 26%
E. None of these

Option “C” is correct.

Let MP=5x

CP=3x

Discount= d

5x * (100 – d)/100=3x * 120/100

500 – 5d=360

D = 28%
82. A shopkeeper marks the price of the article is 20% above its cost price and also offers 10% of the discount. Find the profit percentage?

A. 10%
B. 8%
C. 12%
D. 14%
E. None of these

Option “B” is correct.

CP = x

SP = x * 120/100 * 90/100 = 1.08x

Profit = 1.08x – x = 0.08x

Profit percentage = 0.08x/x * 100 = 8%
83. The selling price of 8 articles is equal to the cost price of 10 articles. What is the percentage profit in selling the articles?

A. 15%
B. 12%
C. 20%
D. 25%
E. 28%

Option “D” is correct.

S.P of 8 articles = C.P of 10 articles

S.P of 1 article = C.P of (5/4) article

Let C.P of 1 article be Rs 4

S.P of 1 article = (5/4)*4 = Rs. 5

So, percentage profit = ((5 – 4)/4)*100% = 25%

2x=5200

x=2600

A. Rs.12000
B. Rs.14000

D. Rs.18000
E. None of these

Option “C” is correct.

MP = 50000

Discount = 50000 – 34000 = 16000
87. A shopkeeper offers a discount of 10%. If the ratio of the marked price to cost price is 6:5, what is the profit or loss percentage?

Profit percentage = ((27x/25) – x) / x * 100

= 8%

B. 240
C. 620
D. 540
E. None

1560 = 2x

x = 780

Profit percentage = (612 – 576)/576 * 100

= 6.25%
