Find the loss if
Cost Price = ₹4,554 and Selling Price = ₹4,432
Loss = C.P. – S.P.
Therefore, Loss = ₹4554 – ₹4432
=₹122
Find the profit if
Selling Price = ₹5,775 and Cost Price = ₹4,543
Profit = S.P. – C.P.
Therefore, Profit = ₹5775 – ₹4543
= ₹1,232
What is the formula for finding the cost price when loss is given?
CP = SP + loss
What is the formula for finding the selling price when profit is given?
SP = Profit + CP
What is selling price?
The price at which a shopkeeper sells an article is called the selling price.
What is cost price?
The price at which a shopkeeper buys an article is called the cost price.
What is the formula for finding the loss incurred?
Loss = CP - SP
What is the formula for finding the profit earned?
Profit = SP - CP
What is the value of word unit?
One
What symbol is used for paisa?
p
Alia bought a music system for 
16,112. She sold it for 15,000. Find her profit or loss amount.
Cost price of music system = 16,112
Selling Price = 15,000
Since C.P. > S.P., she incurred a loss.
Loss = C.P. – S.P.
= 16,112 - 15,000
= 1,112
James sold his air conditioner for 17,086 at a profit of 1029. Find the cost price of the air conditioner.
Selling price of the air conditioner = 17,086
Profit = 1,029
Cost Price = Selling Price – Profit
= 17,086 - 1,029
= 16,057
A second hand scooter was sold for 16700, at a loss of 1230. Find the cost price of the scooter.
Selling price of the scooter = 16,700
Loss = 1,230
Cost price = selling price + loss
= 16,700 + 1,230
= 17,930
A TV was bought for ₹19,221 and sold at a loss of ₹1,210. Find the selling price.
Cost price of TV = ₹19,221
Loss = ₹1,210
Selling price = cost price loss
= ₹19,221 - ₹1,210
= ₹18,011
Find the loss.
Cost Price = ₹3,103 and Selling Price = ₹2,775
Loss = C.P. – S.P.
Therefore, Loss = ₹3,103 – ₹2,775
= ₹328
Joy bought registers at the rate of ₹420 a dozen. He sold all the registers for ₹ 38 each. Find his profit or loss amount.
Cost price of 12 registers = ₹ 420
Cost price of 1 register = ₹ (420 ÷ 12)
= ₹ 35
Selling price of one register = ₹ 38
Since S.P. > C.P., Joy earned a profit.
Profit = Selling Price – Cost Price
= ₹ 38 - ₹ 35
= ₹ 3
Total profit = ₹ (3 x 12) = ₹ 36
Hence, Joy earned a profit of ₹ 36.
Tia bought a computer for 16,770 and spent 210 on its transportation. After using it for 6 months, she sold it for 15,211. Find the profit or loss amount.
Total cost price = Cost price of computer + Cost of transportation
= 16,770 + 210
= 16,980
Selling price = 15,211
Since S.P. < C.P., Tia incurred a loss.
Loss = Cost Price – Selling Price
= 16,980 - 15,211
= 1,769
Hence, Tia earned a profit of 1,769.
Tom bought 18 kg of rice at the rate of ₹22 per kg and 23 kg of rice at the rate of ₹20 per kg. He mixed the two varieties and sold the mixture at the rate of ₹21 per kg. Find the profit or loss amount.
Cost price = ₹(18 x 22) + ₹(23 x 20)
= ₹396 + ₹460
= ₹856
Selling price = ₹(18 x21) + ₹(23 x 21)
= ₹378 + ₹483
= ₹861
Since S.P. > C.P., Tom earned a profit.
Profit = ₹861 - ₹856 = ₹5
Hence, Tom earned a profit of ₹5
Rachel purchased an old car for 67,012. She spent 3450 on repairs and paid 2300 for its insurance. Then she sold it to a mechanic for 74,900. Find the profit or loss amount.
Total cost price = Cost price of car + Cost of
repair + Cost of insurance
= 67,012 + 3450 + 2300
= 72,762
Selling price = 74,900
Since S.P. > C.P., Rachel earned a profit.
Profit = Selling Price – Cost Price
= 74,900 - 72,762
= 2,138
Hence, Rachel earned a profit of 2,138.
Margaret bought a sofa for 10,114 and spent 120 for its transportation. Then she sold it for 9,573. Find the profit or loss amount.
Total cost price = Cost price of sofa + Cost of transportation
= 10,114 + 120
= 10,234
Selling price = 9,573
Since C.P. > S.P., Margaret incurred a loss.
Loss = CP - SP
= 10,234 - 9,573
= 661
Hence, Margaret suffers a loss of 661.
