Profit and Loss Exercise 8.1 Solution :
Question no – (1)
Solution :
Cost Price = 65/25
= 2.60 Rs
Sell = 3.50 Rs
∴ Selling Price,
= (3.50 × 25)
= 87.5 Rs
∴ Profit,
= (87.5 – 65)
= 22.5 Rs
So, shopkeeper will profit 22.5 Rs.
Question no – (2)
Solution :
Cost Price of pen drive = 210 Rs.
Selling Price of pen drive = 250 Rs.
∴ Profit = (250 – 210)
= 40 Rs.
Hence, the profit will be 40 Rs.
Question no – (3)
Solution :
Selling price of cell phone = 8200 Rs.
Make a profit of = 540 Rs.
∴ Cost Price will be = (selling price – profit)
= (8200 – 540)
= 7660 Rs.
So, the cost price of the cell phone will be 7660 Rs.
Question no – (4)
Solution :
Cost price of the bat = 990 Rs.
Make a loss = 77 Rs
∴ Selling price = (cost price – loss)
= (990 – 77)
= 913 Rs.
Therefore, the selling price of the bat will be 913 Rs.
Question no – (5)
Solution :
Chocolate buy total,
= 30/3
= 10 pieces.
Selling price of total,
= 24/2
= 12 Rs.
Now, profit by selling 1 chocolate
= (12 – 10) Rs
= 2 Rs.
Profit and Loss Exercise 8.2 Solution :
Question no – (1)
Solution :
Profit percentage,
= (186 – 150/150 × 100)
= (36/150 × 100)
= 24%
Therefore, the profit percentage will be 24%.
Question no – (2)
Solution :
Cost price of banana,
= 48/12
= 4 Rs.
Selling price of banana,
= (3.80 × 12)
= 45 Rs
So, loss percent,
= (3/48 × 100)
= 6.25%
Therefore, the loss percent will be 6.25%.
Question no – (3)
Solution :
Cost price of the dress = 600 Rs
Selling price of the dress = 690 Rs.
So, profit percent,
= (690 – 600/600 × 100)
= (90/600 × 100)
= 15%
Hence, the profit percent will be 15%.
Question no – (4)
Solution :
Selling price of cosmetics = 1550 Rs.
Cost price of cosmetics,
= (1550 + 310)
= 1860 Rs.
∴ Loss percent,
= (310/1860 × 100)
= 16.67%
Thus, the loss percent will be 16.67%.
Profit and Loss Exercise 8.3 Solution :
Question no – (1)
Solution :
(a) Cost price = Rs 750, profit = 10%
∴ Selling Price,
= (750 × 110/100)
= 825 Rs.
Hence, the selling price will be 825 Rs.
(b) Cost price = Rs 600, loss = 9%
∴ Selling Price,
= (600 × 91/100)
= 546 Rs.
So, the selling price will be 546 Rs.
(c) Cost price = Rs 1000, loss = 2%
∴ Selling Price,
= (1000 × 98/100)
= 980 Rs.
Hence, the selling price will be 980 Rs.
(d) Cost price = Rs 350, overhead expenses = Rs 50, profit = 15%
∴ Total cost price,
= (350 + 500)
= 400 Rs
Now, Selling Price,
= (400 × 115/100)
= 460 Rs.
Thus, the selling price will be 460 Rs.
Question no – (2)
Solution :
Cost price of the television set = 15,000 Rs
Make a profit = 12%
∴ Selling Price,
= (1500 × 112/100)
= 16800 Rs.
Therefore, the selling price of the television set will be 16800 Rs
Question no – (3)
Solution :
Selling price at a loss of 6%
= (500000 × 94/100)
= 470,000 Rs
Now, selling price at a profit of 6%

= 530,000 Rs.
Therefore, the selling price of the car will be 530, 000 Rs.
