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,
Overhead expenses = Rs 150
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%
