A shopkeeper buys an article at ` 12000 and spends 10% of cost price as a transport. He marked price 20% above the price at which he buy and sells at mark marked price, find his profit percent.

Selling price = 1.2 x 12000 = 14400

Cost price = 1.1 x 12000 = 13200

Profit = 14400 - 13200 =1200

Profit % = (1200/13200) x 100 =300/33 =100/11 = 9 1/11 %

Answer is b

A dishonest dealer claims to sell a product at its cost price . He uses a counterfeit weight which is 20% less than the real weight . Further he added 20% impurities to the product . Find the net profit percentage of the dealer !

Hello Tarishi ,

Assume 100g costs 100 and adds 20% impurity

100g will become 120g

now instead of using 100 gm weigh he is using 80 gm weight

so 100g weight using counterfeit weight becomes (120/ 80 ) x 100 = 150 .

Hence profit percentage => 50%

Dev bought 100 kg rice for RS 1100 and sold it at a loss of as much money as he received for 20kg of rice. At what price did he sell the rice?

Hello Richa

We know ,

Selling Price = Cost Price - Loss

Hence , SP of 100 kg = CP of 100 kg - SP of 20 kg

SP of 120 kg = CP of 100 kg

SP : CP = 10 : 12

Hence SP of 100 kg rice = 10 x 1100/12

or Rs 55/6 per kg

let diameter of can be 10 and h be 1

earlier

v= 10*10*1= 100kg

now,

v=9*9*1 =81 kg

now let 1 kg = 1 rs.

earlier we were selling 100kg for 100rs

now we will sell 81 kg for 100 rs

means c.p =81

s.p =100

profit % =(19/81)*100 =23.47 (aprox)

earlier we were having zero profit now 23.47 so change =23.47

The previous profit percentage is not known, so we cannot calculate the increase in profit percentage.

Hence , Option D

A dishonest shopkeeper cheats at the time of purchasing by 20% and at the time of selling by 35% using wrong weights and sells at the cost price.find his profit %

Is it 84.6% ?

Make a cheating of 20% while buying item means while buying he brought item worth Rs 120 in Rs. 100

Now at the time of selling he cheats 35% . So he sells item worth Rs 120 in price of 120 x (100/65) =Rs 184.6

hence profit percentage becomes : 84.6% .

One year payment to a servant is rs. 200 and one shirt. The servant leaves after 9 months and recieves Rs. 120 and a shirt. find the price of the shirt.

a. 80

b. 100

c. 120

d. Can't be determined

Let the price of the shirt be x .

Total yearly income = 200 + x.

Monthly = (200 + x)/12

9 months income = [(200 + x)/12] × 9

Now ,

120 + x = [(200 + x)/12] × 9

x = 120 .

Alternate Approach :

Loss of ₹80 in 3 months so in 12 months => ₹320

Contract is 200 + shirt.

So Shirt = 320 - 200 = ₹120

Deb ought 100kg of rice for Rs. 1100 and sold it at a loss of as much money as he received for 20kg of rice. At what price did he sell the rice?

c. 9.16

d. 9

Same question has been posted earlier... Got the solution...thanks!

PFA the solution

solution please!

Let label price be 100

Trader gets 19% discount so c.p for him =81

Apply m.p/c.p= (100+profit)/(100-discount)

Profit= 20% discount=10%

M.p/81= 120/90

M.p= 108

So 8% above label price option b is correct

solution please!

find the solution in discussion of 22nd question

solution please.

Please provide the solution for question 24 and question 27.

24th

previously scale was 100( assumed value) now it becomes 125 let price of 1 unit =1rs

he is giving 125 unit and getting the price for 100 unit { cp for him=125,sp=100}

loss=(25/125)*100=20% (it can be treated as discount)

he gives discount 10%

successive discount of 20% and 10% =28%

apply mp/cp=(100+profit)/(100-discount)

let cp=100x

mp/100x=108/72

mp=150x

so 50% above cp

27h answer is 10% ?

Solution to the 27th Question :

let 100 items cost 100

Rajesh will take away 110 items

Hence , CP of Rakesh => 110

Marked price for Rajesh : 100 x 121/90

SP : 100 x 121 /90 x 90/100 = 121

Percentage profit : ( 121 - 110)/110 x 100 = 10%

When a producer allows 36% commission on the retail price of his product he earns a profit of 8.8% . What would be his profit % if the commission is reduced by 24% ?

Answer is 49.6 ?

yes sir , could you give the explanation as well ?

Treat commission as the discount he will give and apply mp/cp= (100+profit)/(100-discount)

In first case p=8.08 and commission is 36

Mp/cp= 108.8/64

In 2nd case commission reduces by 24 means it becomes 12 and ratio of mp/cp remains same so

108.8/64=(100+new profit)/88

100+ new profit=149.6

New profit= 49.6
