Question: A man sold an article for tk 247.50.thereby gaining `(12) 1/2`%. The cost of the article was:
A
Tk 225

B
Tk 224

C
Tk 220

D
Tk 210

Note: Here S.P = Tk 247.50, Loss=Tk `(25)/2` %, So C.P= Tk `((100)/(100+(25)/2) xx 247.50)` =Tk '(200)/225xx247.50' therefore C.P= Tk 220

Question: A shopkeeper brought an article for tk 319.60. Approximately, at what price should be sell the article to make 25% profit?
A
Tk400

B
Tk450

C
Tk500

D
Tk600

Note: S.P= tk 125% of Tk 319.60 =tk`((125)/100xx319.60)` =tk399.50 =tk 400(approx)

Question: There would be 10% loss if a toy is sold at tk 10.80 per price. At what price should it be sold to earn a profit of 20%?
A
Tk 12

B
Tk 12.96

C
Tk 14.40

D
None

Note: Here, `90:10.80` = `120 : x` or, `(90)/10.80` = `120/x` 0r, x =`(120xx10.80)/90` =14.40 Hence,S.P= Tk 14.40

Question: By selling an article for tk 19.50, a dealer makes profit of 30%. By how much should he increase his selling price so as to make a profit of 40%?
A
Tk 1.50

B
Tk 1.75

C
Tk 2

D
Tk 3

Note: Here, `130:19.50` = `140 : x` or, `(130)/19.50` = `140/x` 0r, x =`(140xx19.50)/130` =21 Hence,S.P to be increased = Tk (21-19.50) =tk1.50

Question: Rahim buy mangoes at the rate of 3 kg for tk 21 and sell them at 5kg for tk 50. To earn tk 102 as profit, he must sell:
A
26 kg

B
32 kg

C
34 kg

D
56 kg

Note: Rate of buy =tk 7 per kg Rate of selling =tk 10 per kg To gain tk 3 , he must buy = 1kg To gain tk 120 , he must buy = `(1/3xx102)kg = 34 kg.

Question: If books brought at price ranging from tk 200 to tk 350 are sold at the price ranging from tk 300 to tk 425, what is the greatest possible profit that might be made in selling eight books?
A
Tk 400

B
Tk 600

C
Cannot be determined

D
None of this

Note: Least C.P= tk `(200xx8)` = tk 1600 Greatest S.P= Tk `(425xx8)`= tk 3400 Required profit = tk`(3400-1600)` =tk 1800

Question: The cost price of 20 articles is the same as selling price of 15 articles, The profit percent in the transaction is:
A
25

B
30

C
`33 1/3`

D
50

Note: Let C.P of each article = tk 1 C.P of 15 article = tk 15 S.P of 15 article = tk 20 Profit % = `(5/15xx100)% = `33 1/3`%

Question: A man sells 320 mangoes at the cost price of 400 mangoes his gain percent is:
A
10 %

B
15 %

C
20 %

D
25 %

Note: Let C.P of each mango be tk 1 C.P of 320 mangoes = tk 320 S.P of 320 mangoes = tk 400 Profit % = `((80)/320xx100)`% = 25%

Question: If the cost price of 12 tables is equal to the selling of 16 tables the loss percent is :
A
15 %

B
20 %

C
25 %

D
30 %

Note: Let C.P of each Table be tk 1 C.P of 16 Tables = tk 16 S.P of 16 Tables = tk 12 Loss % = `(4/16xx100)`% = 25%

Question: If the selling price of 18 articles is equal to the selling price of 16 tables, the loss percent is :
A
`16 2/3` % gain

B
`14 2/7` % gain

C
`16 2/3` % Loss

D
`14 2/7` % Loss

Note: Let C.P of each article be tk 1 C.P of 18 articles = tk 18 S.P of 18 articles = tk 21 Gain % = `(3/18xx100)`% = `16 2/3`%
