Profit and Loss Exercise 12.1 Solution

Question no – (1)

Solution :

(i) Here, we have,

Cost Price (C.P) = Rs 1200,

Selling Price (S.P) = Rs 1350,

Profit/Loss = ?

Profit = 1350 – 1200

= 150

(ii) Here, we have,

Cost Price (C.P) = Rs 980,

Selling Price (S.P) = Rs 940,

Profit/Loss = ?

Loss = 980 – 940

= 20

(iii) Here, we have,

Cost Price (C.P) = Rs 720,

Selling Price (S.P) = ?,

Profit = Rs 55.50

Selling Price (S.P)

= 720 + 55.50

= 775.50

(iv) Here, we have,

Cost Price (C.P) = ?,

Selling Price (S.P) = 1254,

Loss = Rs 32

Cost Price (C.P)

= 1254 + 32

= 1286

Question no – (2)

Solution :

(i) C.P.= Rs 1265, S.P.= Rs 1253, Loss = Rs 12

Explanation :

Cost Price (C.P) = Rs 1265,

Selling Price (S.P)= Rs 1253

Loss = 1255 – 1253

= 12

(ii) C. P = Rs 300, S.P. = Rs 450. Profit = Rs 150

Explanation :

Selling Price (S.P) = Rs 450.

Profit = Rs 150

Cost Price (C.P) = ?

Cost Price (C.P),

= 450 – 150

= 300

(iii) C.P. = Rs 3355, S.P. = Rs 7355, Profit = Rs 4000

Explanation :

Cost Price (C.P) = Rs 3355,

Selling Price (S.P) = Rs 7355,

Profit = Rs ?

Profit = 7355 – 3355

= 4000

(iv) C.P. = Rs 2395.50, S.P. = Rs 2390, loss = Rs 32

Explanation :

Selling Price (S.P) = Rs 2390,

loss = Rs 32

Cost Price (C.P) = ?

Cost Price (C.P)

= 2390 + 5.50

= 2395.50

Question no – (3)

Solution :

(i) Here, we have,

Cost Price (C.P) = Rs 4560,

Selling Price (S.P) = Rs 5000

Profit,

= (500 – 4560)/5560 × 100%

= 440/5360 × 100

= 9.65%

Hence, the Profit will be 9.65%

(ii) Here, we have,

Cost Price (C.P) = Rs 2600,

Selling Price (S.P) = Rs 2470

Loss %,

= 2600 – 2470/2600 × 100

= 130/2600 × 100

= 5%

Thus, the loss percent will be 5%

(iii) Here, we have,

Cost Price (C.P) = Rs 332,

Selling Price (S.P) = Rs 350

Profit,

= 350 – 332/332 × 100

= (18/332 × 100)%

= 5.42%

Hence, the profit will be 5.42%

(iv) Here, we have,

Cost Price (C.P) = Rs 1500,

Selling Price (S.P) = Rs 1500

Profit,

= 1500 – 1500

= 0

Therefore, not profit not loss.

Question no – (4)

Solution :

(i) According to the question,

Cost Price (C.P) = Rs 4000

Gain = Rs 40.

Gain%,

= 40/4000 × 100

= 1%

Therefore, gain percent will be 1%.

(ii) Given in the question,

Selling Price (S.P) = Rs 1272

loss = Rs 328

Cost Price (C.P) = 1272 + 328

= 1600

Loss% |

= 328/1600 × 100

= 20.5%

The0refore, the loss percent is 20.5%

(iii) From the question we get,

Selling Price (S.P) = Rs 1820

Gain = Rs 420.

Cost Price (C.P)

= 1820 – 420

= 1400

Gain% will be,

= (420/1400 × 100)%

= 30%

Thus, the gain percent will be 30%.

Question no – (5)

Solution :

(i) Here, we have,

Cost Price (C.P.) = Rs 2300,

Overhead expenses = Rs 300 and

Gain = Rs 260.

Cost Price (C.P)

= 2300 + 300

= 2600

Gain%

= (2600/2600 × 100)

= 10%

(ii) Here, we have,

Cost Price (C.P) = Rs 3500,

Loss = Rs 146

Cost Price (C.P),

= 3500 + 150

= 3650

Loss% = 146/3650 × 100

= 4%

Question no – (6)

Solution :

Total Cost Price (C.P)

= 600 × 250 + 1000

= 150000 + 1000

= 1,15,000

His Profit,

= 7 × 151000/100

= 10570

And the selling price is,

= Rs 151000 + 10570

= 161570

Therefore, total profit will be Rs. 10570 and the selling price of rice will be Rs. 161570

Question no – (7)

Solution :

Price of 4 dozen pencil,

= 10.80 × 4

= 43.20

We know,

4 dozen = 48 piece

Selling price,

= 48 × 80

= 38.40

Loss,

= 43.20 – 38.40

= 4.8

Loss %,

= 4.8/43.20 × 100

= 48 × 100/4320 × 10/× 100

= 100/9%

= 11.111%

Therefore, Naresh loss percent will be 11.111%

Question no – (8)

Solution :

Price of one orange,

= 26/12

= 13/6

Costing price for 5 orange,

= 13/6 × 5

= 65/6

Selling price = 13

Profit = 13 – 65/6

= 78 – 65/6

= 13/6

Profit percent,

= (13/6/65/6 × 100) %

= (13/65 × 100) %

= 20%

Thus, Vendor’s gain percent will be 20%

Question no – (9)

Solution :

First, Costing price,

= 365000 + 135000

= 500,000

Now, the Selling price = 5,50,000

Profit = 50000

Profit percentage,

= 50000/500,000 × 100

= 10%

Therefore, Mr. Virmani’s gain percent will be 10%

Question no – (10)

Solution :

As per the question,

Costing price of the watch = Rs 840

Selling price of the watch = Rs 910

Profit,

= 910 – 840 Rs

= 70 Rs

Profit percentage,

= 70/840 × 100

= 25/3%

Thus, Shikha’s profit percent will be 25/3%.

Question no – (11)

Solution :

As per the question we know,

Cost price = 120

Profit = 10%

Gain,

= 10/100 × 120

= 12

Selling price,

= 120 + 12

= 132

Therefore, the selling piece of the toy will be Rs. 132

Question no – (12)

Solution :

According to the question,

Costing price for each banana = 135/50

∴ Profit = 20 × 135/50 × 45/ × 100

= 20 × 135 × 45/ 50 × 100

= 2430/100

= 24.3 per each

Selling price,

= 135 + 24.3

= 159.3

He should sell per dozen,

= 159.3/45

= 3.6 per dozen

Therefore, Harish will need to sell remaining bananas at 3.6 per dozen.

Question no – (13)

Solution :

Costing price,

= 50 × 6.4

= 320

Broken egg price,

= 20 × 55

= 1100

Selling price,

= 50 × 12 × 59 – 1100

= 33,000 – 1100

= 31900 paise

= ₹ 319

So she losses,

Loss% = (1/320 × 100)

= 10/32%

= 5/6%

Therefore, her loss percent is 5/6%

Question no – (15)

Solution :

Selling Price (S.P.) = 230

Let, profit = x

x/230 – x × 100 = 15

= 230 × 15 – 15x = 100x

= 100x + 15x = 230 × 15

= x = 230 × 15/115

= x = 30

Profit = 30

Cost price,

= (230 – 30)

= 200

Thus, Rs. 200 is the C.P. and the actual profit is Rs. 30

Question no – (16)

Solution :

In the given question,

Profit = 10%

Cost Price = 200

Profit,

= (10/100 × 200)

= 20

He sells it for

= (200 + 20)

= 220

Therefore, he sell the at Rs. 220

Question no – (18)

Solution :

Let profit = x

x/240 – x × 100 = 20

= 10x = 24 × 20 – 20x

= 100x + 20x = 240 × 20

= x = 240 × 20/120

= 40

Profit = 40

Cost price,

= (240 – 40)

= 200

If the man sold it for 275 then, Profit,

= 275 – 200/200 × 100

= (75/200 × 100) %

= 37.5%

Therefore, his profit will be 37.5%
