The producerproduces a goods at some certain cost. When those goods are sold at a higher price than the production price, then there is profit. And, if the goods are sold at lower price than production cost, then he suffers a loss.
Thus, profit = Selling price - Cost price
or,Profit = S.P - C.P
Loss = Cost Price - Selling Price
or, Loss= C.P - S.P
For example:
If Renu bought a book for Rs 500 and sold it for Rs 600, then she made a profit of Rs 100 i.e profit = Rs 100
Similarly, if Ritesh bought a machine for Rs 200 and sold it for Rs 100, then he suffered a loss of Rs 100. i.e loss = Rs 200 - Rs 100 = Rs 100 (loss)
For the purpose of comparison, we usually express the actual profit or loss as a percentage of a cost price.
For example; Samikshya sold a bag for Rs 60 which costs Rs 50 and shoes sold for Rs 110 which costs Rs 100. In each case, the shopkeeper makes a profit of Rs 10. It seems that in both cases profit is equally gained.
But in percentage we have:
In the first case, profit percentage = \(\frac{10}{ 50}\) x 100 = 20 %
In the second case, profit percent = \(\frac{10}{100}\) x 100 = 10 %
Hence, in the first case, she made more profit than in the second case, it is better and accurate method of comparison.
Have a look at these formulas:
Percentage profit = \(\frac{actual\;profit}{C.P}\) x 100
Percentage loss = \(\frac{actual\;loss}{C.P}\) x 100
Examples
.
Solution:
Given information,
Cost Price (CP) = Rs 28
Selling Price (SP) = Rs 35
Here,
Actual Profit = SP - CP = Rs 35 - Rs28 = Rs 7
Now,
Percentage Change = \(\frac{actual profit}{CP}\) × 100
= \(\frac{7}{28}\)× 100
= 25%
Solution;
Given information,
Cost Price (CP) = Rs 60
Selling Price (SP) = Rs 50
Here,
Actual Loss = CP - SP
= Rs 60 -Rs 50
= Rs 10
Now,
Percentage Loss = \(\frac{actual loss}{CP}\)× 100
= \(\frac{10}{60}\)×100
= 16 \(\frac{2}{3}\) %
Solution:
Let the cost price be Rs x.
Then, profit = 30% of x
= \(\frac{30}{100}\)× x
= \(\frac{3x}{10}\)
Now,
CP = SP - Profit
or, x = 65 - \(\frac{3x}{10}\)
or, x + \(\frac{3x}{10}\) = 65
or, \(\frac{10x+3x}{10}\) = 65
or, 13x = 650
or, x = \(\frac{650}{13}\)
\(\therefore\) x = 50
Hence, cost of the book = Rs 50
Solution:
Selling price of sari = Rs 1350
Profit (P) = Rs 150
Cost price of sari (CP) =?
We know that,
Profit = SP - CP
or, 150 = 1350 - CP
or, CP = 1350 -150
or, CP = 1200
∴ Cost Price (CP) of sari = Rs 1200
Solution:
Given,
Cost Price of the Calculator (CP) = Rs 760
Loss = Rs 50
Selling Price (SP) = ?
We know that,
Loss = CP - SP
or, 50 =Rs 760 - SP
or, SP = Rs 760 - Rs 50
or, SP = Rs 710
∴ Selling Price of the Calculator (SP) = Rs 710
Solution:
Given information,
Marked Price = Rs 450
Discount amount = 20% of RS 450
= \(\frac{20}{100}\)× 450
= Rs 90
Here
Selling Price = Marked price - Discount amount
= Rs 450 - Rs 90
= Rs 360
Solution:
Given information,
Marked Price = Rs 250
Selling Price (SP) = Rs 200
Discount = MP - SP
= Rs 250 - Rs 200
= RS 50
Here,
Discount Percentage = \(\frac{discount}{MP}\)× 100
= \(\frac{50}{250}\)× 100
= 20%
Solution:
Given information,
Selling Price = Rs 342
Let the marked price be x.
Then,
Discount amount = 10% of x
= \(\frac{10x}{100}\)
= \(\frac{x}{10}\)
Marked Price = SP + Discount amount
or, x = 342 + \(\frac{x}{10}\)
or, x - \(\frac{x}{10}\) = 342
or, \(\frac{10x -x}{10}\) = 342
or, 9x = 3420
\(\therefore\) x = \(\frac{3420}{9}\) 380
Hence, the marked price of the Article = Rs 380
Solution:
Given information,
Selling Price (SP) before VAT = Rs 4500
Selling Price (SP) after VAT = Rs 5000
VAT amount = SP with VAT - SP before VAT
= Rs 5400 - Rs 5000
= Rs 400
\(\therefore\) VAT rate = \(\frac{VAT amount }{SP before VAT}\)× 100
= \(\frac{400}{5000}\)× 100
= 8%
Solution:
Given information,
Marked Price = Rs 1,250
Discount Percent = 5%
Actual Price of watch = MP - Discount Percentage
= Rs 1,250 - Rs 1,250 × \(\frac{5}{100}\)
= Rs 1,250 - Rs 62.50
= Rs 1,187.50
∴ Actual Price of watch = Rs 1,187.50
Solution:
Given information,
Marked Price of Radio(MP) = Rs 1160
Selling Price after discount (SP) = Rs 1044
Now,
Discount = MP - SP
= Rs 1160 - Rs 1044
= Rs 116
∴ Discount Percentage = \(\frac{Discount Amount}{MP}\)× 100
= \(\frac{116}{1160}\) × 100
= 10%
Solution:
Given information,
Marked Price (MP) = Rs 210
Discount Percent = 12%
Discount amount = 12% of MP
= 210× \(\frac{12}{100}\)
= Rs 25.20
∴ Actual Price of the Book = Marked Price - Discount
= Rs 210 - Rs 25.20
= Rs 184.80
