1. Given the following values, find the unknown values: 
(i) C.P. = Rs 1200, S.P. = Rs 1350 Profit/Loss? 
(ii) C.P. = Rs 980, S.P. = Rs 940 Profit/Loss =? 
(iii) C.P. = Rs 720, S.P. =?, Profit = Rs 55.50 
(iv) C.P. =? S.P. = Rs 1254, Loss = Rs 32 
 
Solution: 
(i) Given CP = Rs. 1200, SP = Rs. 1350 
Clearly CP < SP. So, profit. 
Profit = SP – CP 
= Rs. (1350 – 1200)  
= Rs. 150 
 
(ii) Given CP = Rs. 980, SP = Rs. 940 
Clearly CP > SP. So, loss. 
Loss = CP - SP 
= Rs. (980 – 940)  
= Rs. 40 
 
(iii) CP = Rs. 720, SP =?, profit = Rs. 55.50 
Profit = SP – CP 
55.50 = SP – 720 
SP = (55.50 + 720)  
= Rs. 775.50 
 
(iv) CP =?, SP = Rs. 1254, loss = Rs. 32 
Loss = CP – SP 
32 = CP – 1254 
CP = (1254 + 32)  
= Rs. 1286 
 
2. Fill in the blanks in each of the following: 
(i) C.P. = Rs 1265, S.P. = Rs 1253, Loss = Rs …….

Solution: 
(i) Given CP = Rs. 4560, SP = Rs. 5000 
Here, clearly SP > CP. So, profit. 
Profit = SP – CP  
= Rs. (5000 – 4560)  
= Rs. 440 
Profit % = {(Profit/CP) x 100} %  
= {(440/4560) x 100} %  
= {0.0965 x 100} %  
Profit % = 9.65% 
 
(ii) Given CP = Rs. 2600, SP = Rs. 2470. 
Here, clearly CP > SP. So, loss. 
Loss = CP – SP  
= Rs. (2600 – 2470)  
= Rs. 130  
Loss % = {(Loss/CP) x 100} % 
= {(130/2600) x 100} % 
= {0.05 x 100} %  
Loss % = 5% 
 
(iii) Given CP = Rs. 332, SP= Rs. 350. 
Here, clearly SP > CP. So, profit. 
Profit = SP – CP  
= Rs. (350 – 332)  
= Rs. 18  
Profit% = {(Profit/CP) x 100} %  
= {(18/332) x 100} % 
= {0.054 x 100} %

Profit = Rs. (7355 – 3355)  
= Rs. 4000 
 
(iv) C. P. = Rs 2395.50 
 
Explanation: 
Given CP = ?, SP = Rs. 2390, loss = Rs. 5.50 
Loss = CP – SP 
5.50 = CP – 2390  
= Rs. (5.50 + 2390)  
 
 
 
 
 
 
 
 
= Rs. 2395.50 
 
3. Calculate the profit or loss and profit or loss percent in each of the following cases:

Solution: 
(i) Given CP = Rs. 4560, SP = Rs. 5000 
Here, clearly SP > CP. So, profit. 
Profit = SP – CP  
= Rs. (5000 – 4560)  
= Rs. 440 
Profit % = {(Profit/CP) x 100} %  
= {(440/4560) x 100} %  
= {0.0965 x 100} %  
Profit % = 9.65% 
 
(ii) Given CP = Rs. 2600, SP = Rs. 2470. 
Here, clearly CP > SP. So, loss. 
Loss = CP – SP  
= Rs. (2600 – 2470)  
= Rs. 130  
Loss % = {(Loss/CP) x 100} % 
= {(130/2600) x 100} % 
= {0.05 x 100} %  
Loss % = 5% 
 
(iii) Given CP = Rs. 332, SP= Rs. 350. 
Here, clearly SP > CP. So, profit. 
Profit = SP – CP  
= Rs. (350 – 332)  
= Rs. 18  
Profit% = {(Profit/CP) x 100} %  
= {(18/332) x 100} % 
= {0.054 x 100} %  
 
 
 
 
 
 
 
 
Profit % = 5.4% 
 
(iv) Given CP = Rs. 1500, SP = Rs. 1500

4. Find the gain or loss percent, when: 
(i) C.P. = Rs 4000 and gain = Rs 40. 
(ii) S.P. = Rs 1272 and loss = Rs 328 
(iii) S.P. = Rs 1820 and gain = Rs 420. 
 
Solution: 
(i) Given CP = Rs. 4000, gain = Rs. 40 
Gain % = {(Gain/CP) x 100) %  
= {(40/4000) x 100} %  
= (0.01 x 100) % 
Gain % = 1% 
 
(ii) Given SP = Rs. 1272, loss = Rs. 328 
Loss = CP – SP 
Hence, CP = Loss+ SP  
= Rs. 328 + Rs. 1272  
= Rs. 1600 
Loss % = {(Loss/CP) x 100} %  
= {(328/1600) x 100%  
Loss % = 20.5% 
 
(iii) Given SP = Rs. 1820, gain = Rs. 420 
Gain = SP – CP  
CP = 1820 – 420  
= Rs. 1400

Solution: 
(i) Given CP = Rs. 1200, SP = Rs. 1350 
Clearly CP < SP. So, profit. 
Profit = SP – CP 
= Rs. (1350 – 1200)  
= Rs. 150 
 
(ii) Given CP = Rs. 980, SP = Rs. 940 
Clearly CP > SP. So, loss. 
Loss = CP - SP 
= Rs. (980 – 940)  
= Rs. 40 
 
(iii) CP = Rs. 720, SP =?, profit = Rs. 55.50 
Profit = SP – CP 
55.50 = SP – 720 
SP = (55.50 + 720)  
= Rs. 775.50 
 
(iv) CP =?, SP = Rs. 1254, loss = Rs. 32

Profit = Rs. (7355 – 3355)  
= Rs. 4000 
 
(iv) C. P. = Rs 2395.50 
 
Explanation: 
Given CP = ?, SP = Rs. 2390, loss = Rs. 5.50 
Loss = CP – SP 
5.50 = CP – 2390  
= Rs. (5.50 + 2390)  
 
 
 
 
 
 
 
 
= Rs. 2395.50 
 
3. Calculate the profit or loss and profit or loss percent in each of the following cases:

Solution: 
(i) Given CP = Rs. 4560, SP = Rs. 5000 
Here, clearly SP > CP. So, profit. 
Profit = SP – CP  
= Rs. (5000 – 4560)  
= Rs. 440 
Profit % = {(Profit/CP) x 100} %  
= {(440/4560) x 100} %  
= {0.0965 x 100} %  
Profit % = 9.65% 
 
(ii) Given CP = Rs. 2600, SP = Rs. 2470. 
Here, clearly CP > SP. So, loss. 
Loss = CP – SP  
= Rs. (2600 – 2470)  
= Rs. 130  
Loss % = {(Loss/CP) x 100} % 
= {(130/2600) x 100} % 
= {0.05 x 100} %  
Loss % = 5% 
 
(iii) Given CP = Rs. 332, SP= Rs. 350. 
Here, clearly SP > CP. So, profit. 
Profit = SP – CP  
= Rs. (350 – 332)  
= Rs. 18  
Profit% = {(Profit/CP) x 100} %  
= {(18/332) x 100} % 
= {0.054 x 100} %  
 
 
 
 
 
 
 
 
Profit % = 5.4% 
 
(iv) Given CP = Rs. 1500, SP = Rs. 1500

So, neither profit nor loss. 
 
4. Find the gain or loss percent, when: 
(i) C.P. = Rs 4000 and gain = Rs 40. 
(ii) S.P. = Rs 1272 and loss = Rs 328 
(iii) S.P. = Rs 1820 and gain = Rs 420. 
 
Solution: 
(i) Given CP = Rs. 4000, gain = Rs. 40 
Gain % = {(Gain/CP) x 100) %  
= {(40/4000) x 100} %  
= (0.01 x 100) % 
Gain % = 1% 
 
(ii) Given SP = Rs. 1272, loss = Rs. 328 
Loss = CP – SP 
Hence, CP = Loss+ SP  
= Rs. 328 + Rs. 1272  
= Rs. 1600 
Loss % = {(Loss/CP) x 100} %  
= {(328/1600) x 100%  
Loss % = 20.5% 
 
(iii) Given SP = Rs. 1820, gain = Rs. 420 
Gain = SP – CP  
CP = 1820 – 420  
= Rs. 1400 
Gain % = {(Gain/CP) x 100} %  
= {(420/1400) x 100 %  
Gain % = 30% 
  
5. Find the gain or loss percent, when: 
(i) C.P. = Rs 2300, Overhead expenses = Rs 300 and gain = Rs 260. 
 
 
 
 
 
 
 
 
(ii) C.P. = Rs 3500, Overhead expenses = Rs 150 and loss = Rs 146 
 
Solution: 
(i) Given CP = Rs. 2300, overhead expenses = Rs. 300 and gain = Rs. 260 
We know that Gain % = {(Gain/ (CP + overhead expenses)} x 100  
= {260/ (2300 + 300} x 100 
= {260/2600} x 100  
Gain = 10% 
 
(ii) Given CP = Rs. 3500, overhead expenses = Rs. 150 and loss = Rs. 146 
We know that Loss % = {(Loss/ (CP + overhead expenses)} x 100  
= {146/ (3500+ 150)} x 100 
= {146/3650} x 100  
= 14600/3650  
Loss = 4% 
 
6. A grain merchant sold 600 quintals of rice at a profit of 7%. If a quintal of rice cost 
him Rs 250 and his total overhead charges for transportation, etc. were Rs 1000 find 
his total profit and the selling price of 600 quintals of rice. 
 
Solution: 
Given Cost of 1 quintal of rice = Rs. 250 
Cost of 600 quintals of rice = 600 x 250 = Rs. 150000 
Overhead expenses = Rs. 1000 
CP = Rs. (150000 + 1000) = Rs. 151000 
Profit % = (Profit/CP) x 100 
7 = (Profit /151000) x 100 
Profit = 1510 x 7  
Profit = Rs. 10570 
Now SP = CP + profit  
= Rs. (151000 + 10570)  
SP = Rs. 161570
