A salesman's terms were changed from a flat commission of 5 % on all his sales to a fixed salary of Rs. 1000 plus 2.5 % commission on all sales exceeding Rs. 4000. if his remuneration as per the new scheme was Rs. 600 more than by the first scheme. What were his sales worth?

  1. Rs. 8000

  2. Rs. 10,000

  3. Rs. 12,000

  4. Rs. 15,000


Correct Option: C
Explanation:

Let his sales were worth Rs. "x"
So $[1000\, +\, 2.5 \%\, \times\, (x\, -\, 4000) ]\, -\, 5\, \% \times\, x\, =\, 600$


$1000\, +\, \displaystyle \frac{1}{40}\, (x\, -\, 4000)\, -\, \displaystyle \frac{5}{100}\, \times\, x\, =\, 600$

$1000\, +\, \displaystyle \frac{x}{40}\, -\, 100\, -\, \displaystyle \frac{5x}{100}\, =\, 600\times x$


$x = Rs. 12,000$ 

An agent gets a commission of $2.5 \%$ on the sales of cloth. If on a certain day, he gets $\text { Rs. } 12.50$ as commission, the cloth sold through him on that day is worth? 

  1. $\text { Rs. } 250$

  2. $\text { Rs. } 500$

  3. $\text { Rs. } 750$

  4. $\text { Rs. } 1250$


Correct Option: B
Explanation:
Let the cloth sold by the agent $= x$
Comission of sales of cloth $= 2.5\%$
Commission $=\ Rs 12.50$
According to the problem,
$2.5 \%\, of\, x =\ Rs 12.50$
$\dfrac{2.5}{100}\times x = 12.50$ 
$x =\dfrac{12.50\times 100}{2.5}$
$x =\dfrac{1250}{2.5}$
After cancellation we get,
$x =\ Rs. 500$

An auctioneer charges $8\%$ for selling a house. If the house is sold for $Rs. 2,30,500$. Find the charges of the auctioneer.

Explanation:

Given that:

Sudha's commission $4500-1500=Rs.3000$
Sudha gets $Rs.800$ for the sales of $Rs.10,000$
$Rs.3000=\dfrac{15}{4}\times 800$

Hence,
The total sale $=\dfrac{15}{4}\times 10000=Rs.37500$

$= 6125$ rupees

Therefore, the commission paid by Kumar is Rs. $6125$.

At an electronics store Sara earns a 5% commission on her sales The table here shows her sales for four weeks What was Sara's total commission for these four weeks?
                               Sara's Sales 

Week      1      2     3     4
Sales Rs.1920 Rs.1680 Rs.3360 Rs.2640
  1. Rs 12

  2. Rs 40

  3. Rs 120

  4. Rs 480


Correct Option: D
Explanation:

Total sales for 4 weeks  $ = 1920+1680+3360+2640 = Rs.9600$

The commission that sara earns $ = \frac { 5 }{ 100 } (9600)= 480$

Pia is a sales representative for a printer company. She sells two models of printers - Model P and Model Q.
Last month she sold a total of $120$ printers
The ratio of Model P printers sold to Model Q printers sold was $3:5$.
If Pia is paid a $Rs. 25$ commission for every Model P printer sold and a $Rs. 20$ commission for every Model Q printer sold, what was her total commission last month? 

  1. $Rs. 1480$

  2. $Rs. 2475$

  3. $Rs. 2625$

  4. $Rs. 2760$


Correct Option: C
Explanation:

Number of P printers sold = $P$

Number of Q printers sold = $Q$
Commission for each P printer sold = $Rs.25$
Commission for each Q Printer sold = $Rs.20$
Given that $\frac { P }{ Q } =\frac { 3 }{ 5 } $
so we can assume that $P = 3x, Q=5x$
Total printers sold $= P+Q = 120$
$\Rightarrow 8x= 120 , x=15$
Total money earned $= (25)(3)(15) + (20)(5)(15) = 1125+1500 = 2625$

 

If a commission $10\%$ given on the marked price of a book, the publisher gain $20\%$ . If the commission is increased to $15\%$, the gain of publisher is

  1. $\dfrac {91}{6} \%$

  2. $14\%$

  3. $\dfrac {40}{3} \%$

  4. $\dfrac {50}{3} \%$


Correct Option: C
Explanation:

Let CP $= 100$ and Marked Price be $x$
SP $= 100 + 20\%$ of $100=100+\dfrac{20}{100}\times 100 = 120$
$10\%$ commission was given on SP.
$\Rightarrow$ SP $= x - 10\%$ of $x$
$\Rightarrow 120 = x - \dfrac{10x}{100}$
$\Rightarrow 120 = \dfrac{9x}{10}$
$\Rightarrow 9x = 1200$
$\Rightarrow x = \dfrac{1200}{9} =$ Rs. $133.33$
MP $= 133.33$
If $15\%$ commission was given, then
$\Rightarrow$ SP $= 133.33 - 15\% of 133.33=133.33+\dfrac{15}{100}\times 133.33$
$\Rightarrow$ SP $= 133.33 - 20$
$\Rightarrow$ SP $= 113.33$
Gain $ = 113.33 - 100=13.33$
$\%$ gain  $=\dfrac{13.33}{100}\times 100= 13.33 \%$

If a commission of $10$ $\%$ is given on MP of book , the publisher gains $20$ $\%$. If the commission is increase to $15$ $\%$ , the gain $\%$ is?

  1. $10$

  2. $20$

  3. $15$

  4. $\dfrac {40}{3}$

  5. None of these


Correct Option: D
Explanation:

Let MP $= 100$
SP after giving $10$ $\%$ commission $= 100 - 10$ $\%$ of $100 = 90$.
Let CP $= x$
Gain $ = 20$ $\%$
Now, $+x + 20$ $\%$ of $x = 90$
$\dfrac {120 x }{100} = 90$
$x= 75$
CP $= 75$
If $15$ $\%$ commission was given, then SP $= 85$
Gain $= 85 - 75 = 10$
Percent gain  $= \dfrac {(10 \times 100)}{75} = \dfrac {40}{3} = 13.33$ $\%$.

Remo, who works in a high-end jewellery store, earns a base pay of $\$ 10.00$ per hour plus a certain percent commission on the sales that he helps to broker in the store. Remo worked an average of $35$ hours per week over the past two weeks and helped to broker sales of $\$ 5,000.00$ worth of jewellery during that same two week period. If Remo's earnings for the two-week period were $\$ 850.00$, what percent commission on sales does Remo earn? 

  1. $1\%$

  2. $2\%$

  3. $3\%$

  4. $4\%$


Correct Option: C
Explanation:

Given that Remo works in jewelry store he earns a base pay of $\$10$ per hours plus a certain percent commission on sale and Remo worked an average of $35$ hours in week.

Then Ramo total base pay for two weeks $=$ $35\times 2\times 10=700$ dollars.
But Remo earning for two weeks were $\$850$ including percent  commission of sale $\$5000$.
So, percent  commission of sale $\$5000=850-700=150$ dollar
Then percent on sale $=$ $\dfrac{150}{5000}\times 100=3$ $\%$

Amit used to earn $7$% commission on every piece of mobile he sells. Calculate amount of his commission if he sells a mobile phone for $Rs.90000$?

$\cfrac{7}{100}\times 90000$
$=Rs.6300$

A salesman is appointed on a fixed monthly salary of Rs. $1,500$/- together with a commission at $5$% on the sales over Rs. $10,000$/- during a month. If his monthly income is Rs. $2,050$/-, find his sales during that month. 

  1. Rs. $22,000$

  2. Rs. $20,000$

  3. Rs. $23,000$

  4. Rs. $21,000$


Correct Option: D
Explanation:

$\Rightarrow$   Commission at $5\%$ on the sales over Rs. $10,000$ 

$\Rightarrow$ Monthly income - monthly salary.= Rs.$2050-$Rs.$1500=$Rs.$550.$
$\Rightarrow$  The sales over Rs.$10,000=550\times \dfrac{100}{5}=$Rs.$11000.$

$\Rightarrow$  Total sales during the month = Rs.$10,000+$Rs.$11,000=$Rs.$21,000$

If a commission $15$% given on the marked price of a book, the publisher gain $19$%. If the commission is not there, the gain of publisher is

  1. $30$%

  2. $20$%

  3. $40$%

  4. $50$%


Correct Option: C
Explanation:
Cost price=CP, Selling price=SP
Marked Price=MP
If $15$% commission on MP is given
$SP=MP-\cfrac { 15 }{ 100 } MP=\cfrac { 85 }{ 100 } MP\rightarrow 1$
Under this condition gain is $19$%
$SP=CP+\cfrac { 19 }{ 100 } CP=\cfrac { 119 }{ 100 } CP\rightarrow 2$
If there is no commission
$S{ P }^{ 1 }=MP$ (MP and CP will not change)
But from $1$ and $2$
$\cfrac { 85 }{ 100 } MP=\cfrac { 119 }{ 100 } CP$
$MP=\cfrac { 119 }{ 85 } CP$
$S{ P }^{ 1 }=MP=\cfrac { 119 }{ 100 } CP=\left( \cfrac { 85+34 }{ 85 }  \right) CP$
$S{ P }^{ 1 }=CP=\cfrac { 34 }{ 85 } CP=CP+\cfrac { 2 }{ 5 } CP$
$=CP+40$% of CP
$\therefore$ Gain for publisher is $40$%

A salesman is allowed $5\%$ commission on the total sales made by him plus a bonus of $1\%$ on the excess of his sale over Rs. $20,000$/-. If the total earnings are Rs. $1,450$/- on commission alone, find his total earnings?

  1. Rs. $100$

  2. Rs. $90$

  3. Rs. $80$

  4. Rs. $110$


Correct Option: B
Explanation:
Given that he makes $1450$ on commission alone.
$\Rightarrow 5$% of Total sales$=1450$
$\cfrac { 5 }{ 100 } \times $ Total$=1450$
Total$=29000$
Given that he earns $1$% on excess of sales of $20000$
Earnings$=1%$ of excess
$=\cfrac { 1 }{ 100 } \times \left( 29000-20000 \right) $
$=90$
$\therefore $He earns Rs.$90$

In a museum, the entrance ticket costs Rs. $250$. In Vacation , the cost of the ticket is reduced, there by increasing the sale by $50$%. but it was found that the collection is decreased by $17.5$ %. what is the deduction in the ticket price?

  1. Rs. $100$

  2. Rs. $112.5$

  3. Rs. $1000$

  4. Rs. $1225$


Correct Option: B
Explanation:
Let there is sell of $100\ tickets.$

So, total Collection $= 250 \times 100 = Rs.\ 25,000$ 

Now, 
Total ticket sale $= 100 + 50\%\ of\ 100 = 150$

This effected $17.5\%$ decrease in collection.

So, Collection after increased sale,
$= 25000 - 17.5\%\ of\ 25000 $

$= Rs.\ 20, 625$

In vacation time per ticket price,
$= \dfrac{20625}{150}$

$ = Rs. 137.5$

Decreased in each ticket price,
$= 250 - 137.5 = Rs.\ 112.5$

Hence, this is the answer.

If a commission of $10$% is given on MP of book , the publisher gains $20$% . If the commission is increase to $20$% , the gain % is?

  1. $5$

  2. $6.66$

  3. $3.33$

  4. $8$


Correct Option: B
Explanation:

$S.P=M.P-$commission$\times M.P$

$S.P=C.P+$ gain$\times C.P$
Let $C.P=Rs.100$
For gain $=20\%, S.P=Rs.120$
and commission$=10\%,MP=Rs.133.33$
For commission$=20\%$ and $M.P=Rs133.33$
$S.P=Rs.106.66$
$C.P=Rs.100$
$\implies $ gain$=\cfrac{S.P-C.P}{C.P}\times 100=6.66\%$

If a commission $20$% given on the marked price of a book, the publisher gain $60$% . If the commission is not there, the gain of publisher is

  1. $100$

  2. $90$

  3. $60$

  4. $80$


Correct Option: A
Explanation:
Let discount be $D$
$SP=MP-D\times MP$
for $D=20\%$
$SP=(1-0.2)\times MP=0.8MP$
Again
Gain$=\cfrac{SP-CP}{CP}\times 100$
For gain$=60\%$ and $SP=0.8MP$
$CP=MP/2$
If $D=0$
$SP=MP$ and $CP=MP/2$
$\implies$Gain$=\cfrac{SP-CP}{CP}\times 100=100\%$


If a commission of $5$% is given on MP of book , the publisher gains $26.66$% . If the commission is increase to $15$% , the gain % is?

  1. $10$

  2. $13.33$

  3. $16.66$

  4. $20$


Correct Option: B
Explanation:
$S.P=M.P-$commission$\times M.P$
$M.P=$Marked price
$S.P=C.P+$gain$\times C.P$
Let$M.P=Rs.100$
for commission$=5\%,S.P=Rs.95$ 
and gain$=26.66\%,C.P=Rs.75$
for commission$=15\%,M.P=Rs.100$ 
$S.P=Rs.85$
$C.P=Rs.75$
$\implies$ gain$=\cfrac{S.P-C.P}{C.P}\times 100=13.33\%$

A salesman is appointed on a fixed monthly salary of Rs. $1,500$/- together with a commission at $5$% on the sales over Rs. $10,000$/- during a month. If his monthly income is Rs. $2,050$/-, find his sales during that month.

  2. Rs. $20,000$

  3. Rs. $21,000$

  4. Rs. $19,000$


Correct Option: C
Explanation:

Commission at $5\%$ on the sales over Rs. $10,000$/- 

$=$ monthly income $-$ monthly salary 
$=$ Rs. $2050-1500$ 
$=$ Rs. $550$/- 

The sales over Rs. $10,000$ $=$ Rs. $550 \times $ $\dfrac {100}{5}$ $=$ Rs. $11,000$
Total sales during the month 
$=$ Rs. $(10,000 + 11,000) =$ Rs. $21,000$  

If a commission of $10\%$ is given on the written price of an article, the gain is $20\%$. If the commission is increased to $20\%$, the gain is

  1. $6\dfrac{2}{3}\%$

  2. $7\dfrac{1}{4}\%$

  3. $12\dfrac{1}{2}\%$

  4. $13\dfrac{1}{3}\%$


Correct Option: A
Explanation:

List price $=Rs\ 100$ commission $10\%$

$SP=90\ Rs$ Gain $28\%$
$CP\ Rs \left(\dfrac{100}{120}\times 90\right)=0.75$
$SP=Rs\ 80$
New gain $\%=\dfrac{5}{75}\times 100=6\dfrac{2}{3}$
$=\dfrac{20}{3}\%$


A salesman is appointed on a fixed monthly salary of Rs. $1,500$/- together with a commission at $5$% on the sales over Rs. $10,000$/- during a month. If his monthly income is Rs. $2,500$/-, find his sales during that month. 

  1. $20,000$

  2. $10,000$

  3. $30,000$

  4. $40,000$


Correct Option: A
Explanation:
Fixed salary$=1500$
Monthly income$=2500$
Income from commission$=2500-1500$
$=1000$
Given $5$% of total sale equals commission he gets
$\Rightarrow 5$% of Total sales$=1000$
$\cfrac { 5 }{ 100 } \times T.S=1000$
T.S$=20,000$
$\therefore$ His sales during that month was Rs.$20,000$

A sum of Rs. $15500$ is lent out into two parts, one at $8\%$ and another one at $6\%$. If the total annual income is Rs. $1060$, the money lent at $8\%$ is

A tax payer is exempted of income tax for the first Rs. $100000$ of his annual income but for the rest of the income he has to pay a tax at the rate of $20\%$. If he paid Rs. $3160$ as income tax for a year his monthly income is

  1. Rs. $11580$

  2. Rs. $103160$

  3. Rs  $13610$

  4. Rs. $9650$


Correct Option: D
Explanation:

Let the annual income of the person be Rs. $x$ 

Then $20\%$ of $(x - 100000) = 3160$
$\displaystyle \Rightarrow x-100000=\frac{3160\times 100}{20}=15800$
$\displaystyle \Rightarrow x=115800$
$\displaystyle \therefore$ Monthly income $=$ Rs. $\dfrac{115800}{12}=$ Rs. $9650$

Prices register an increase of $10\%$ on food grains and $15\%$ on other items of expenditure. If the ratio of an employees expenditure on food grains and other items be $2 : 5$, by how much should his salary be increased in order that he may maintain the same level of consumption as before his present salary being Rs. $2590$

  1. Rs. $ 323.75$

  2. Rs. $ 350$

  3. Rs. $ 360.50$

  4. Rs. $ 351.50$


Correct Option: D
Explanation:

Given that the expenses on food : other items $=2 : 5$.

His salary $=$ Rs. $2590$.
$\therefore $ expenses on food $=$ Rs. $\dfrac { 2 }{ 5+2 } \times 2590=$ Rs. $740$ and 
the expenses on other items $=$ Rs. $(2590-740)=$ Rs. $1850$.
Now the rise in price for rice at $10\%=$ Rs. $740\times \dfrac { 10 }{ 100 } =$ Rs. $74$ and
the rise in price for other items at $15\%=$ Rs. $1850\times \dfrac { 15 }{ 100 } =$ Rs. $277.5.$ 
$\therefore $ the net rise in expenses $=$ Rs. $(74+277.5)=$ Rs. $351.5$.
$\therefore $ his salary should be increased by Rs. $351.5$ to cope with the present situation.

  3. Rs. $56678.40$

  4. None of these


Correct Option: B
Explanation:

Let Mrs. Sharma's monthly salary be Rs.$x$ 

Then $15\%$ of $x =$ Rs. $4428$
$\displaystyle \Rightarrow x=$ Rs. $\dfrac{4428\times 100}{15}=$ Rs. $29520$
$\displaystyle \therefore$ Total monthly amount invested by Mrs. Sharma $= (15\% + 18\% + 9\%)$ of Rs. $29250$
$\displaystyle =42\%$ of Rs. $29250$
$=\dfrac{42}{100}\times 29250$
$=$ Rs. $12398.40$
