Solutions

General Section

4 a) The marked price of a mobile is Rs 12 600 and 10% discount is allowed.

(i) Find the discount amount.

(ii) Find the selling price of the mobile.

(iii) How much is its price with 13% VAT?

Solution:

Here,

MP = $Rs 12 600$

Discount percentage (d%) = $10\%$

(i) discount amount = $d\% of MP = 10% of 12600$

$= Rs 1 260$

(ii) selling price = $MP - discount$

$= 12 600 - 1260$

$= Rs 11340$

(iii) Selling price with 13% VAT = $SP ( 1 + \frac{13}{100} )$

$= 11340 * \dfrac{113}{100}$

$= Rs 12814.20$

5 a) The marked price of a lady bag is Rs 4 800. If a customer is given 10 % discount, how much does he/she pay with 15% VAT?

Solution:

For a lady bag,

Marked Price (MP) = Rs 4800

Discount percentage (d%) = 10%

VAT percentage (VAT%) = 15%

To find: Selling Price with VAT (SP with VAT) = ?

We know,

SP = $MP ( 1 - \frac{d%}{100})$

Also,

SP with VAT = $SP(1 + \frac{VAT%}{100}$

From above two formulae, we get,

SP with VAT = $MP(1 - \frac{d%}{100})(1 + \frac{VAT%}{100}$

$= MP ( 1 - \frac{10}{100})(1 + \frac{15}{100})$

$= MP × \dfrac{100-10}{100} × \dfrac{100+15}{100}$

$= 4800 × \dfrac{90}{100} × \dfrac{113}{100}$

$= \dfrac{48 × 9 × 115}{10}$

$= Rs 4968$

Hence, the required selling price of the lady bag including VAT after discount is Rs 4968.

6 a) The marked price of a woolen sweater is Rs 1 750. If the shopkeeper allows 20% discount and makes a profit of Rs 150, at what price did he purchase the sweater?

Solution:

For a woolen sweater,

Marked Price (MP) = Rs 1750

Discount percentage (d%) = 20%

Profit amount (P) = Rs 150

To find: Cost Price (CP) = ?

We know,

Selling Price = $MP( 1 - \frac{d%}{100})$

$= MP ( 1 - \frac{20}{100})$

$= 1750 × \dfrac{80}{100}$

$= Rs 1400$

Now,

Cost Price = SP - P

$or, CP = 1400 - 150$

$\therefore CP = Rs 1250$

Hence, the required cost price of the woolen seater is Rs 1250.

6 c) Mr. Rai bought a radio for Rs 2 000 and fixed its price so that after giving 20 % discount he made 10 % profit. Find the fixed price of the radio.

Solution:

For a radio,

Cost Price (CP) = Rs 2000

Discount percentage (d%) = 20%

Profit Percentage (P%) = 10%

We know,

The fixed price is the marked price.

And,

Selling Price = $CP(1 + \frac{P%}{100})$

Selling Price = $MP(1 - \frac{d%}{100})$

From above two formulae, we get,

$CP ( 1 + \frac{P%}{100} = MP(1 - \frac{d%}{100})$

$or, 2000 ( 1 + \frac{10}{100}) = MP ( 1 - \frac{20}{100}$

$or, 2000 × \dfrac{110}{100} = MP × \dfrac{80}{100}$

$or, 2200 = MP × \dfrac{80}{100}$

$or, MP = 2200 × \dfrac{100}{80}$

$\therefore MP = Rs 1760$

Hence, the required fixed price of the radio is Rs 1760.

6 e) The marked price of an article is Rs 2 800 which is 40% above the cost price. If it is sold by allowing 20% discount, what  will be the profit percent?

Solution:

For an article,

Marked Price (MP) = Rs 2800

Marked Price (MP) = CP + 40% of CP

$or, 2800 = CP ( 1 + 40%)$

$or, 2800 = CP ( 1 + \frac{40}{100})$

$or, 2800 = CP × \frac{140}{100}$

$or, CP = \dfrac{2800×100}{140}$

$\therefore CP = Rs 2000$

And,

Selling price (SP) = $MP (1 - \frac{d%}{100}$

$= MP ( 1 - \frac{20}{100})$

$= 2800 × \frac{80}{100}$

$= Rs 2240$

Now,

Profit percentage (P%) = $\dfrac{SP - CP}{CP} × 100%$

$= \dfrac{2240 - 2000}{2000} × 100%$

$= \dfrac{240}{2000} × 100%$

$= 12%$

Hence, the required profit percentage in the trade of the article is 12%.

7 a) A trader marks the price of his/her good 40% above the cost price and allows 20% discount. If his/her purchase price of an item is Rs 6 000, how much should a customer pay for it levying 13% VAT?

Solution:

Given,

Cost price (CP) = Rs 6000

Marked Price (MP) = $CP(1 + 40%)$

$= CP ( 1 + \frac{40}{100})$

$= 6000 × \frac{140}{100}$

$= Rs 8400$

Discount percentage (d%) = 20%

Now,

Selling Price (SP) = $MP ( 1 - \frac{d%}{100})$

$= MP ( 1 - \frac{20}{100})$

$= 8400 × \frac{80}{100}$

$= Rs 6720$

And,

VAT percentage (VAT%) = 13%

SP with VAT = $SP ( 1 + \frac{VAT%}{100})$

$= SP ( 1 + \frac{13}{100})$

$= 6720 × \frac{113}{100}$

$= Rs 7593.60$

Hence, a customer should pay Rs 7593.60 with 13% VAT.

7 c) The marked price of an article is Rs 4 500. After allowing some percent of discount and levying 10% VAT it is sold at Rs 4 400, find the discount percent.

Solution:

For an article,

Marked Price (MP) = Rs 4500

VAT percent (VAT%) = 10%

SP with VAT = Rs 4400

Discount percent = d%

We know,

SP = $\dfrac{SP with VAT}{100 + \frac{VAT%}{100}}$

$= \dfrac{4400}{100 + \frac{10}{100}}$

$= \dfrac{4400}{\frac{110}{100}}$

$= 4400 × \frac{100}{110}$

$= Rs 4000$

And,

d% = $\dfrac{MP - SP}{MP} × 100%$

$= \dfrac{4500 - 4000}{4500} × 100%

$= 11.11%$

Hence, the required discount percentage in the marked price is 11.11%.

8 a) A grocer fixed the price of his goods 25% above the cost price. If he/she sold a box of noodles allowing 5% discount, find his profit percent.

Solution:

Let the Cost Price be represented by CP.

Here,

Marked Price = $CP ( 1+ \frac{25}{100})$

$= CP  × \frac{125}{100}$

$= \frac{5CP}{4}$

And,

When discount percentage (d%) = 5%,

SP = MP ( 1 - $\frac{d%}{100}$)

$= \frac{5CP}{4} × (1 - \frac{5}{100})$

$= \frac{5CP}{4} × \frac{95}{100}$

$= \frac{95CP}{80}$

Now,

Profit percentage = $\dfrac{SP -CP}{CP} × 100%$

$= \dfrac{ \frac{95 CP}{80} - CP}{CP} × 100%$

$= \dfrac{ \frac{95 CP - 80 CP}{80}}{CP} × 100%$

$= \dfrac{15CP}{80} × \dfrac{1}{CP} × 100%$

$= \dfrac{15}{80} × 100%$

$= 18.75%$

Hence, the required profit percentage in the given transaction is 18.75%.
