Q 1-"A trader marked his goods at 20% above the cost price . He sold half he stock at the marked price . one quarter at a discount of 20% on he marked price and he rest at a discount of 40% on the marked price . His total gain is :"A - 2%B - 4.50%C - 13.50%D - 15%
```Answer - A

Explanation

"Let C.P. of whole stock = Rs. 100.
Then Marked price of whole stock = Rs. 120.
M.P. of 1/2 stock = Rs. 60,
M.P. of 1/4 sock = Rs. 30
∴ Total S.P. = Rs. .[60 + (80% of 30) + (60% of 30)]
= Rs. (60 + 24 + 18)= Rs. 102.
Hence, gain % = (102 - 100)% = 2%
"
```
Q 2-Shopkeeper fixes the marked price of an item 35% above its cost price . The percentage of discount allowed to gain 8% is :A - 20%B - 27%C - 31%D - 43%
```Answer - A

Explanation

"Let C.P. = Rs. 100.
Then , marked price = Rs. 135,
S.P. = Rs. 108.
∴ Discount % = ([27/135]×100)% = 20%
"
```
Q 3-A trader marked the selling price of an article at 10% above the cost price .At the time of selling , he allows certain discount and suffers a loss of 1% . He allowed a discount of :A - 9%B - 10%C - 10.50%D - 11%
```Answer - B

Explanation

"Let C.P. = Rs. 100, marked price = Rs. 110, S.P. = Rs. 99
∴ Discount % = ([11/110]×100)% = 10%
"
```
Q 4-A tradesman gives 4% discount on the marked price and gives a article free for buying every 15 article and thus gains 35% . The marked price is above the cost price by :A - 20%B - 39%C - 40%D - 50%
```Answer - D

Explanation

"Let the C.P. of each article be Rs. 100
Then , C.P. of 16 articles = Rs. (100 x 16) = Rs. 1600
S.P. of 15 articles = Rs. (1600×[135/100]) = Rs. 2160.
S.P. of each article = Rs. 2160/15 = Rs. 144
If S.P. is Rs. 96, marked price = Rs. 100.
If S.P. is Rs. 144. marked price = Rs. ([100/96]×144)= Rs. 150.
∴ Marked price = 50% above C.P.
"
```
Q 5-By selling an article a 2/5 of the marked price , here is a loss of 25% . The ratio of he marked price and the cost price of the article isA - 2 : 5B - 5 : 2C - 8 : 15D - 15 : 8
```Answer - D

Explanation

"Let cost price = Rs. 100.
Then 2/5 of (marked price) = 75
⇒ Marked price = Rs. ([75×5]/2) =Rs.375/2
∴ Required ratio = [375/2] : 100 = 375 : 200 = 15 : 8
"
```
Q 6-A shopkeeper earns a profit of 12% on selling a book at discount on the printed price. The ratio of the cost price to the printed price of the book is :A - 45 : 56B - 50 : 61C - 55 : 69D - 99 : 125
```Answer - A

Explanation

"Let cost price be Rs. 100.
The S.P. = Rs. 112
Let printed price be Rs. x 90% of x = 112 ⇒ x= (112×[100/90]) = Rs. 1120/9
∴ Required ratio = 100 : [1120/9] = 900 : 1120 = 45 : 56.

Q 7-At what price should a shopkeeper mark a radio that costs him Rs. 1200 in order that be may offer a discount of 20% on the marked price and still make a profit of 25%A - Rs. 1675B - Rs. 1875C - Rs. 1900D - Rs. 2025
```Answer - B

Explanation

"C.P. = Rs. 1200, S.P. = 125% of Rs. 1200
= Rs. ([125/100]×1200)= Rs. 1500
Let marked price be x,
Then , 80% of x = 1500 ⇒ x= (1500×1[00/80]) ⇒ x= (1500×[100/80]) = Rs. 1875
∴ Marked price = 1875.
"
```
Q 8-At what percent above the cost price must a shopkeeper mark his goods so that he gains 20% even after giving a discount of 10% on he marked price ?A - 25%B - 30%C - 100/3%D - 75/2%
```Answer - C

Explanation

"Let C.P. = Rs. 100,
Then, S.P. = Rs. 120.
Therefore,let marked price be Rs. x.
Then , 90% of x = 120 ⇒ x=(120×[100/90]) = 100/3
∴ Marked price = 100/3% above C.P.
"

Q 9-A shopkeeper allows a discount of 10% on the marked price of an item but charges a sales tax of 8% on the discounted price . If the customer pays Rs. 680.40 as the price including he sales tax , then what is the marked price of the itemA - Rs. 630B - Rs. 700C - Rs. 780D - None of these
```Answer - B

Explanation

"Let the marked price be Rs. x .
Then, 108% of 90% of x = 680.40
⇒ [(108/100)×(90x/100)] = 680.40
⇒ x= [(68040 x 100)/(108 x 90)] = Rs. 700.

Q 10-"The cost price of an article is 64% of the marked price . Calculate the gain percent after allowing a discount of 12%."A - 37.50%B - 48%C - 50.50%D - 52%
```Answer - A

Explanation

"Let marked price  = Rs. 100.  Then , C.P. = Rs. 64, S.P. = Rs. 68.

"Marked price = Rs. 300. C.P. = Rs. ([100/120]×300)= Rs. 250.

Sale price = 90% of Rs. 300 = Rs. 270.

∴ Required  gain % = ([20/250]×100)% =  8%"

Q 12-A retailer buys 30 articles from a wholesaler at he price of 27. If he sells them at their marked price ,the gain percent in the transaction is :A - 100/11%B - 10%C - 100/9%D - 50/3%
```Answer - C

Explanation

"Let the marked price of each article be Rs.1

Then ,C.P. of 30 = Rs. 27, S.P. of 30 = Rs. 30

∴   Gain% = ([3/27]×100)% =  1/9 x 100%=100/9 %"
```
Q 13-The price of an article is raised by 30% and then two successive discounts of 10 % each are allowed. Ultimately, the price of he article isA - decreased by 5.3%B - increased by 3%C - increassed by 5.3%D - increased by 10%
```Answer - C

Explanation

"Let the original price  be Rs. 100, Then ,marked price = Rs. 130

Final price =  90% of 90% of Rs. 130 = Rs. ([90/100]×[90/100]×130) =  Rs. 105.30

∴     Increase in price = (105.30 - 100)% =  5.3%"

Q 14-A tradesman makrs his goods 30% above the C.P. . If he allows a discount of 614614% ,then his gain percent isA - 175/8%B - 22%C - 95/4%D - None of these
```Answer - A

Explanation

"Let C.P. be Rs. 100,
Then , marked price = Rs. 130
S.P. = (100−[25/4])% of Rs. 130 = Rs. ([375/400]×130) = 121.875
∴ profit % = (121.875 - 100)% = 21.875% = 21875/1000%=175/8%
"
```
Q 15-A trader marked the price of his commodity so as to include a profit of 25% . He allowed discount of 16% on the marked price . His actual profit was :A - 5%B - 9%C - 16%D - 25%
```Answer - A

Explanation

"Let C.P.  be Rs. 100,  Then ,marked price = Rs. 125

S.P. = 84% of Rs. 125 = Rs. ([84/100]×125) = Rs. 105

∴   profit % =  (105 - 100)% =   5% "
