  1. Rs. $12,750$

  2. Rs. $11,220$

  3. Rs. $10,950$

  4. Rs. $11,475$

Show answer
Correct Option: B
Explanation:

The marked price of T.V. $=Rs.15,000$ 

Price of T.V after $15\%$ discount $=Rs.\left(15,000-\dfrac{15}{100}\times 15000\right)$

                                                      $=Rs.\left(15,000-2250\right)$
                                                      $=Rs.12,750$
Price of T.V. again after $12\%$ discount $=Rs\left(12,750-\dfrac{12}{100}\times 12750\right)$

                                                               $=Rs.\left(12750-1530\right)$
                                                               $=Rs.11,220$

$\therefore$  The price of the T.V if cash purchase is made is $Rs.11,220.$

  4. 31.6%; Rs. 71

Show answer
Correct Option: A,B
Explanation:

Given marked price is Rs 250
Selling price after Ist discount =100-20=80 Rs
Selling price after 1st discount=$\frac{80\times 250}{100}= 200$Rs
Selling price after 2nd discount=Selling price after 2nd discount=$\frac{90\times 200}{100}= 180$Rs
Selling price after third discount=$\frac{95\times 280}{100}= 171$Rs
Total discount = 250-171=79 Rs
% of total discuont =Selling price after 2nd discount=$\frac{79\times 100}{250}= 31.6$%

  1. Rs. 22.40

  2. Rs. 16.80

  3. Rs. 9.80

  4. Rs. 36.40

Show answer
Correct Option: C
Explanation:

M.P. of the shirt = Rs.700 

S.P. of the shirt 1st shoopkeeper = 70% of 94% of Rs.700
$\displaystyle =\frac{70}{100}\times \frac{94}{100}\times Rs.700=Rs.460.60$
S.P. of the shirt offered by the 2nd shopkeeper = 80% of 84% of Rs.700
$\displaystyle =\frac{80}{100}\times \frac{84}{100}\times Rs.700=Rs.470.40$
$\displaystyle \therefore$ 1st shopkeeper offers better discounts and 
Required difference $= Rs.470.40 - Rs. 460.60 = Rs.9.80 $

maths money math different discounts successive discounts problems on discounts

  1. decreased by 5.3%

  2. increased by 3%

  3. increased by 5.3%

  4. increased by 10%

Show answer
Correct Option: C
Explanation:

Let the original price=100 Rs.
Then marked price=130 Rs.
First discount=10%
Then 10% of 130=$\frac{10}{100}\times 130=13  Rs$
Price of article after first discount=$130-13=117  Rs$
Second discount=10%
Then 10% of 117=$\frac{10}{100}\times 117=11.70  Rs.$
Price of article after second discount =$117-11.70=105.30 Rs.$
$\therefore  increase  in  price=105.30-100=5.30$
$increased  percentage=\frac{5.30}{100}\times 100=5.30$
Hence the price of article increased by 5.30 %.

maths money math different discounts successive discounts problems on discounts

  1. $12%$

  2. $14%$

  3. $15%$

  4. $18%$

Show answer
Correct Option: C
Explanation:
Given:
The Marked Price, $MP$ of the watch is $Rs.\ 720$.
The Selling Price, $SP$ of the watch is $Rs.\ 550.80$.
The first discount is $10\%$.


Let the second discount be $x\%$.

According to the question,

$550.8=720\times \dfrac{90}{100}\times \dfrac{(100-x)}{100}$
$55080=(72\times 9)\dfrac{(100-x)}{100}$
$55080=64800-648x$
$x=\dfrac{9720}{648}$
$x=15\%$


Hence, the second discount is $15\%$.

  2. 29%

  3. 30%

  4. 26%

Show answer
Correct Option: A
Explanation:

Let the marked price of an article be Rs. 100
Then first discount on it =Rs. 20
Price after discount =Rs. (100-20)=Rs. 80
Second discount on it =10% of Rs. 80
$Rs.(80\times \frac{10}{100})=Rs.8$
Price after second discount =Rs. (80-8)=Rs. 72
Net selling price =Rs. 72
Single discount equivalent to given successive discounts =(100-72)%=28%

Find the successive discount equivalent to $10\%$ and $5\%$.

  1. $14.5\%$

  2. $15\%$

  3. $15.5\%$

  4. $16\%$

Show answer
Correct Option: A
Explanation:

$\Rightarrow$  Let A = First discount = 10% and B = Second discount = 5%.

$\Rightarrow$  Equivalent Discount = $(A+B)-(\dfrac{A\times B}{100})$

$\Rightarrow$  Equivalent Discount = $(10+5)-(\dfrac{10\times 5}{100})=15-0.5=14.5\%$

  1. $Rs. 3,108$

  2. $Rs. 3,148$

  3. $Rs. 3,200$

  4. $Rs. 3,600$

Show answer
Correct Option: C
Explanation:

Let the marked price be $Rs. 100$
Price after $1st$ discount $= Rs. 87\dfrac {1}{2}$
Price after $2nd$ discount $= Rs. 87\dfrac {1}{2} - 7 \dfrac {1}{2}$% of $87\dfrac {1}{2}$
$\therefore$ Customer pays $= 92\dfrac {1}{2}$% of $Rs. 87\dfrac {1}{2}$
When the customers pay $Rs. 2590$, then the marked price
$= \dfrac {2590\times 100}{92\dfrac {1}{2} \times 87\dfrac {1}{2}} = Rs. 3,200$.

  1. $Rs. 122.50$

  2. $Rs. 125$

  3. $Rs. 128.25$

  4. $Rs. 172.50$

Show answer

Now, second discount$=5\%$
Hence, price after second discount$=135-5\%\ of\ 135=135-6.75=Rs.\ 128.25$
So, he get $Rs.\ 128.25$
