Question 40: A shopkeeper gives 10% discount but uses a false weight which displays 1 kg for every 850g weight. What is the shopkeeper’s net profit/loss if he claims to mark the goods at the cost price?

a) 5.88% profit

b) 6.22% loss

c) 4.56% loss

d) 5.48% profit

As the loss is given as 18%. The selling price would be 82% of the cost price.
S.P. = 82% of Rs. 2600 = Rs. 2132

Let C.P. be Rs. c.

Then, (2160 – c)/c x 100 = (c – 1440)/c x 100
2160 – c = c – 1440

2c = 3600

c = 1800

Required S.P. = 130% of Rs. 1800 = Rs. 1.30 x 1800 = Rs 2340.

Given A’s Cost Price = Rs.250

Then, Cost Price of C can be written as $250\times\frac{130}{100}\times\frac{80}{100} = Rs.260$

Cost Price of the book = $200\times\frac{100}{80} = Rs.250$
Cost Price $= Rs.250$
Required Profit $= 30$%
Required Selling Price $= 250\times\frac{130}{100} = Rs.325$

Let a = discount = -25%
b = Marked up percentage = 16%

Effective profit/loss % = a + b + $\Large\frac{ab}{100}$

$\Rightarrow$ $-25$ $+$ $16$ $+$ $\Large\frac{(-25)\times16}{100}$

$\Rightarrow$ $-9$ $+$ $(-4)$ $=$ $-13$%

$\therefore$ Effective loss % $=$ $13$%

Let the Selling Price of items be ‘SP’

Let the Cost Price of items be ‘CP’

Given 11 CP = 10 SP

$\Rightarrow$ $\large\frac{SP}{CP}$ $=$ $\large\frac{11}{10}$

Subtracting 1 from both sides

$\Rightarrow$ $\large\frac{SP}{CP}$ $-$ $1$ $=$ $\large\frac{11}{10}$ $-$ $1$

$\Rightarrow$ $\large\frac{SP-CP}{CP}$ $=$ $\large\frac{11-10}{10}$ $=$ $\large\frac{1}{10}$

$\therefore$ $\large\frac{SP-CP}{CP}$ $\times$ $100$ $=$ $\large\frac{1}{10}$ $\times$ $100$ $=$ $10$% Profit

Selling price of book $=$ Rs.240.
Loss $=$ 20%
We know that Loss % $=$ $\large\frac{CP-SP}{SP}$ $\times$ $100$

$\Rightarrow$ $20$ $=$ $\large\frac{CP-240}{CP}$ $\times$ $100$

$20$ $=$ $(\large\frac{CP}{CP}$ $-$ $\large\frac{240}{CP})$ $\times$ $100$

$\Rightarrow$ $20$ $=$ (1 – $\large\frac{240}{CP}$) $\times$ $100$

$\Rightarrow$ $1$ $-$ $\large\frac{240}{CP}$ $=$ $\large\frac{1}{5}$

$\Rightarrow$ $\large\frac{240}{CP}$ $=$ $\large\frac{4}{5}$

$\Rightarrow$ CP $=$ $240\times\large\frac{5}{4}$ $=$ Rs.$300$

$\therefore$ Cost price of the book $=$ Rs.$300$

Required profit percentage $=$ $25$%
We know that Profit % $=$ ($\large\frac{SP-CP}{CP}$) $\times$ $100$

$\Rightarrow$ $25$ $=$ ($\large\frac{SP-300}{300}$) $\times$ $100$

$\large\frac{SP}{300}$ $-$ $\large\frac{300}{300}$ $=$ $\large\frac{1}{4}$

$\Rightarrow$ $\large\frac{SP}{300}$ $-$ $1$ $=$ $\large\frac{1}{4}$

$\Rightarrow$ $\large\frac{SP}{300}$ $=$ $\large\frac{5}{4}$

$\therefore$ Required Selling Price of the book $=$ $\large\frac{5}{4}$ $\times$ $300$ $=$ Rs.$375$

In this case it is given that marked up by 40% then
If CP=x,MP=1.4x Given no loss and no profit.

Therefore MP-discount=CP(since SP=CP)

Therefore 1.4x-d=x

d=0.4x
Discount is always calculated on marked price.
Discount percent=$\frac{0.4x}{1.4x}\times 100$
=200/7 %.

Total cost price of the 12 pencils=480 rs
selling price of the 6 pencils =$35 \times 6$
=210
Given profit of 20% on the other 6 pencils and so selling price of the other six pencils =$240\times$ 1.2
=288
Total selling price =210+288
=498 rs
Profit %=$\frac{498-480}{480}\times 100$
=$\frac{15}{4}$

Cost price of TV = Rs. 2000

Profit % = 20%

=> Selling price of TV = $2000+(\frac{20}{100}\times2000)$

= $2000+400=Rs.$ $2400$

Similarly, selling price of radio = $750-(\frac{5}{100}\times750)$

= $750-37.5=Rs.$ $712.5$

Thus, total cost price = $(2000+750)=Rs.$ $2750$

and total selling price = $(2400+712.5)=Rs.$ $3112.5$

$\therefore$ Gain = $3112.5-2750=Rs.$ $362.50$

=> Ans – (B)

$2\frac{1}{2} dozens$ = $\frac{5}{2}\times12$=30 eggs

12 eggs price$\rightarrow$ Rs.20
then 30 eggs price$\rightarrow$ Rs. 50
No. of rotten eggs=6
Remaining eggs=24

Selling price of 12 eggs = Rs.22
Selling price of 24 eggs=$2\times22$=Rs.44

Loss percentage=$\frac{S.P.-C.P.}{C.P}\times100$

=$\frac{50-44}{50}\times100$

=$\frac{6}{50}\times100$=12% loss

In the first transaction :

Cost price for X = Rs. 1,50,000

Profit % = 5%

=> Selling price for X = Cost price of Y = $1,50,000+(\frac{5}{100}\times1,50,000)$

= $1,50,000+7500=Rs.$ $1,57,500$

In the second transaction :

Cost price for Y = Rs. 1,57,500

Loss % = 2%

=> Selling price for Y = Cost price of X = $1,57,500-(\frac{2}{100}\times1,57,500)$

= $1,57,500-3150=Rs.$ $1,54,350$

$\therefore$ Total profit for X = $1,57,500-1,54,350=Rs.$ $3150$

=> Ans – (A)

Selling price of book = Rs. 21

Let cost price = Rs. $x$

=> Loss % = $x\%$

According to ques,

=> $\frac{(x-21)}{x}\times100=x$

=> $100x-2100=x^2$

=> $x^2-100x+2100=0$

=> $x^2-30x-70x+2100=0$

=> $x(x-30)-70(x-30)=0$

=> $(x-30)(x-70)=0$

=> $x=30,70$

$\therefore$ Cost price (in Rs) of the book = Rs. 30 or 70

=> Ans – (C)

Let cost price of article = Rs. $100x$

Profit % = 20%

=> Selling price = $100x+(\frac{20}{100}\times100x)$

= $100x+20x=Rs.$ $120x$

Now, new cost price = $100x+(\frac{40}{100}\times100x)$

= $100x+40x=Rs.$ $140x$

Also, new selling price = Rs. $(120x-24)$

=> Loss % = $\frac{140x-(120x-24)}{140x}\times100=20$

=> $\frac{20x+24}{7x}=\frac{20}{5}$

=> $20x+24=4\times7x$

=> $28x-20x=24$

=> $x=\frac{24}{8}=3$

$\therefore$ Cost price = $100\times3=Rs.$ $300$

=> Ans – (B)

Selling price = Rs. 2700 and loss % = 10%

=> Cost price = $\frac{2700}{(100-10)}\times100$

= $30\times100=Rs.$ $3000$

Profit % = $33\frac{1}{3}=\frac{100}{3}\%$

$\therefore$ Selling price = $3000+(\frac{100}{3\times100}\times3000)$

= $3000+1000=Rs.$ $4000$

=> Ans – (D)

Cost price of each article = Rs. 4000

Profit % on one article = 12.5%

=> Selling price of first article = $4000+(\frac{12.5}{100}\times4000)$

= $4000+500=Rs.$ $4500$

Similarly, selling price of second article = $4000-(\frac{20}{100}\times4000)$

= $4000-800=Rs.$ $3200$

Thus, total cost price = $4000+4000=Rs.$ $8000$

Total selling price = $4500+3200=Rs.$ $7700$

$\therefore$ Overall loss % = $\frac{(8000-7700)}{8000}\times100$

= $\frac{300}{80}=3.75\%$

=> Ans – (B)

Let $\ r_{1} = 2cm,\ r_{2} = 4cm,\ r_{3} = 6cm$

There is a loss of 25% of the material, volume of the remaining spherical ball is given by,

$\frac{3}{4}$ x $\frac{4}{3} \pi ((r_{1})^{3} + (r_{2})^{3} + (r_{3})^{3})$

$\pi (2^{3} + 4^{3} + 6^{3})$ = $\pi (8 + 64 + 216)=288\pi$

Radius of the new ball is given by,

$\frac{4}{3} \pi r^{3}$ = $288\pi$ (or) $r^{3} = 216$ (or) $r = 6cm$

Hence, option A is the correct answer.

As the percentage of profit is equal to percentage of loss,

Profit/loss = (310 – 230) / 2

$\Rightarrow$ 80 / 2 = 40

Cost price = (230 + 40) or (310 – 40) = 270

Loss percentage when selling price is 180 = {(270 – 180) / 270} x 100

$\Rightarrow$ (90/270) x 100 = 100/3 = $33\frac{1}{3}$

Hence, option C is the correct answer.

Let cost price of 1 article is x

Selling price of 318 articles = 212 Rs

Cost price of 318 articles = 318 Rs

Profit% = {(318 – 212) / 318} x 100 = (106/318) x 100

$\Rightarrow$ (5300/159) = $33\frac{1}{3}$

Hence, option B is the correct answer.

Selling price = Rs. 720

Loss % = 25%

=> Cost price = $\frac{720}{(100-25)}\times100$

= $720\times\frac{4}{3}=Rs.$ $960$

Profit % = 25%

=> Selling price = $960+(\frac{25}{100}\times960)$

= $960+240=Rs$ $1200$

=> Ans – (D)

Let cost price = Rs. 100

Markup % = 10%

=> Marked price = $100+(\frac{10}{100}\times100)$

= $100+10=Rs.$ $110$

After discount of 10%, Selling price = $110-(\frac{10}{100}\times110)$

= $110-11=Rs.$ $99$

$\because$ C.P. > S.P., => Loss % = $\frac{(100-99)}{100}\times100=1\%$

=> Ans – (D)

Selling price = Rs. 450 and loss % = 20%

=> Cost price = $\frac{450}{(100-20)}\times100$

= $450\times\frac{5}{4}=Rs.$ $562.50$

$\therefore$ Selling price to gain 20% = $\frac{(100+20)}{100}\times562.50$

= $\frac{6}{5}\times562.50=Rs.$ $675$

=> Ans – (D)

Let C.P. of 1 chair = Rs. $x$ and S.P. of 1 chair = Rs. $y$

According to ques, => $25x=30y$

=> $\frac{x}{y}=\frac{30}{25}=\frac{6}{5}$

Let $x=6$ and $y=5$

$\therefore$ Loss % = $\frac{(x-y)}{x}\times100$

= $\frac{(6-5)}{6}\times100=\frac{50}{3}$

= $16\ \frac{2}{3}\%$

=> Ans – (A)

Selling price = Rs. 31 and loss % = 7%

=> Cost price = $\frac{31}{(100-7)}\times100$

= $\frac{3100}{93}=Rs.$ $\frac{100}{3}$

If selling price = Rs. 35

=> Profit % = $\frac{35-\frac{100}{3}}{\frac{100}{3}}\times100$

= $\frac{(105-100)}{100}\times100=5\%$

=> Ans – (A)

The shopkeeper sells 12kg of potatoes for 63rs i.e 1kg for 5.25rs

Let cost price = 100x. As he gains 5% the equation can be written as,

105x = 5.25rs (or) 100x = 5rs

$\therefore$ Cost price = 5rs

He sells 50 kg of the same potatoes for 247.50rs (or) 1kg = 4.95rs

Gain or loss percentage = $(\frac{4.95 – 5}{5})(100)$ = 0.05 x 100 = -1%

There will be a loss of 1%

Hence, option B is the correct answer.

Let, cost price be 100x then selling price will be 80x

If he sold the article for 200 more then he would earn a profit of 5%

105x = 80x + 200

25x = 200

x = 8

Cost price = 800.

Hence, option A is the correct answer.

Lets us assume that cost price of the watch on which Ram incurred loss = Rs. $x$
Ram incurred a loss of 32 percent hence Ram must had sold it for = Rs. 0.68$x$
We are given that 0.68$x$ = 2448
Therefore $x$ = Rs. 3600
Hence cost price of the other watch = 1.5 * 3600 = Rs. 5400
Total cost incurred to Ram for buying these two watches = Rs. 5400 + Rs. 3600 = Rs. 9000
Ram wants to gain a profit of 8% both transactions combined
Hence selling price of both watches combined = $\frac{100 + 8}{100}\times 9000 = Rs. 9720$
Therefore selling price of other watch = 9720 – 2448 = Rs. 7272

Hence we can say that Ram should sell another watch for Rs. 7272. Hence option A is the correct answer.

Let us assume of cost price of chocolate bar = Rs. $p$

Ram incurred a loss of 27 % hence he must have sold it for = $\frac{100 – 27}{100}\times p$ = Rs. 0.73$p$

Given that $0.73p = 43.80$

Hence cost price of chocolate bar p = $\frac{43.80}{0.73}$ = Rs. 60

To realise a profit of 46 percent Ram should have sold the chocolate bar for = $\frac{100+46}{100}\times 60$ = Rs. $87.60$

Hence we can say that option D is the correct answer.

Cost price of each chair = 3720/3 = Rs. 1240
Profit on one chair = 0.3 * 1240 = Rs. 372
Loss on second chair = 0.12 * 1240 = Rs. 148.8
Loss on third chair = 0.16 * 1240 = Rs. 198.4
Total proft or loss = 372 – 148.8 – 198.4 = Rs. 24.8
Hence, option C is the right answer.

Let us assume that the cost price of the fridge is Rs. $x$.
Ram sold the fridge for Rs. 4851 at a loss of 23%
Hence cost price of fridge = $\frac{4851}{1- 0.23}$ = Rs. 6300

To gain 18% Ram should sell the fridge for = $\frac{100+18}{100}\times 6300$ =Rs. 7434
Hence option C is the correct answer.

Selling price of the laptop on which he incurred loss = Rs. 21360
Hence cost price of the laptop= $\frac{21360}{1 – 0.11}$ = Rs. 24000
He bought both the laptops at same price so total CP of both laptops = 2*24000 = Rs. 48000
He wants to make 7% profit in the entire transaction then
SP of both laptops combined = $\frac{107}{100}\times 48000$ = Rs. 51,360
Therefore selling price of the second laptop = Rs. (51,360 – 21,360) = Rs. 30000

Hence we can say that option A is the correct answer.

Let the cost price for the retailer be Rs. $x$.
If the loss is 15%, the selling price of the calculator is $(1-0.15)x = Rs. 0.85x$
New selling price = $0.8x + 103.4$
Profit % for new selling price = $\frac{0.85x + 103.4 – x}{x}*100$ = 7
$\Rightarrow$ $103.4 – 0.15x = 0.07x$
$\Rightarrow$ $x = Rs. 470$
Hence, option A is the right answer.

Let the CP of each article be Rs. 100x
Then, total CP = 100x * 2 = 200x
SP of the article sold at 27% profit = Rs. 127x
SP of the article sold at 39% loss = Rs. 61x
Total SP of both articles = Rs. (127x + 61x) = Rs. 188x
Since CP > SP, we can say that Satish incurred loss in this transaction.
Net loss incurred = Rs. (200x – 188x) = Rs. 12x
Net profit % = $\frac{12x}{200x}\times 100$ = 6%.
Therefore, option D is the right answer.

Let the selling price of the two boxes be Rs. $x$ each
Cost price of the box sold at 30% profit = Rs. $\frac{x}{1.3}$
Cost price of the box sold at 18% loss = Rs. $\frac{x}{0.82}$
According to the question, $\frac{x}{1.3}$ + $\frac{x}{0.82}$ = $4240$
$\frac{2.12x}{1.066} = 4240$
$x$ = Rs. $2132$
Box with lower cost price = $\frac{2132}{1.3}$ = Rs. $1640$
Hence, option C is the right answer.

For ease of calculation, we can assume that he bought 30 toffees (lcm of 5 and 6)
CP = Rs. 25
SP = RS. 36
Profit = Rs. 11
Profit % = $\frac{11}{25}$* 100% = 44%.
Therefore, option C is the right answer.

Let the CP of each article be Rs. 100
Then, total CP = Rs. 300
SP of each of the two articles sold at 20% profit = Rs. 120
Sp of the article sold at 30% loss = Rs. 70
Total SP = Rs. (120 + 120 + 70) = Rs. 310
Net profit = Rs. (310 – 300) = Rs. 10
Net profit % = 10/300 * 100% = 3.33%.
Therefore, option D is the right answer.

Let the CP be Rs. 100
Then, marked price = Rs. 100 + 25% of Rs 100 = Rs. 125
After the first discount, SP = Rs. 125 – 10% of Rs. 125 = Rs. 112.5
After the second discount, SP = RS 112.5 – 10% of Rs. 112.5 = Rs. 101.25
So, the final SP = Rs. 101.25
Net profit = Rs. 1.25
Net profit % = 1.25%
Hence, option B is the correct answer.

Let the CP of bike be Rs. 100x
SP for Ajay = CP for Raman = Rs 100x + 10% profit = Rs. 110x
SP for Raman = CP for Abir = Rs. 110x + 10% profit = Rs. 121x
SP for Abir = CP for Sumi = Rs. 121x + 10% loss = Rs. 108.9x
It is given that,
108.9x = 10890
=>x = 100
CP for Raman = Rs. 110x = Rs. 11000
Hence, option C is the correct answer.

Let the cost price of 100 cm of cloth be Rs. 100
As the trader is giving 20% discount,
Selling price of 100 cm of cloth = Rs. 80
But, in Rs. 80, he is selling only 80cm of cloth due to the false measuring scale.
CP of 80 cm of cloth = Rs. 80
And SP of 80 cm of cloth = Rs. 80
Profit/Loss = Rs. 0
Hence, option D is the correct answer.
