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 :

= 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%

= (500000 × 106/100)

= 530,000 Rs.

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