Solutions

Maths Quiz (Profit & Loss) for KVS/NVS & CTET Exams_40.1

S2. Ans.(d)
Sol. Here, selling price = Rs. 1850 
Profit percentage = 25% 
∴ Cost price =(Selling price × 100)/(100 + profit%) 
=(1850 × 100)/(100 + 25)=(1850 × 100)/125 
= Rs. 1480 

S3. Ans.(a)
Sol. Here, cost price = Rs. 46000 
Loss percentage = 12% 
∴ Selling price =46000((100-12)/100) 
=(46000 × 88)/100 
= 460 × 88 = Rs. 40480 
Again, cost price = Rs. 40480 
Gain percentage = 12%
∴ Selling price =40480((100 + 12)/100) 
=40480×(112/100) = Rs. 45337.60 
Hence, overall loss = 46000 – 45337.60
= Rs. 662.40 

S4. Ans.(d)
Sol. Here, cost price = Rs. 9600 
Loss percentage = 5%
∴ Selling price = 9600×((100 – 5)/100)
=9600×(95/100) = Rs. 9120 
Again, cost price = 9120 
Gain percentage = 5%
∴ Selling price =9120((100 + 5)/100) 
=(9120 × 105)/100 
= Rs. 9576
Hence, overall loss = 9600 – 9576 
= Rs. 24 

S5. Ans.(d)
Sol. Here, selling price = Rs. 308 
Profit percentage = 12%
∴ Cost price =(308 × 100)/(100 + 12) 
=(308 × 100)/112   
= Rs. 275 
Again, selling price = Rs. 308 
Loss percentage = 12%
∴ Cost price =(308 × 100)/88 
= Rs. 350 
In whole transaction, 
Total SP = 308 × 2 = Rs. 616 
Total CP = 275 + 350 
= Rs. 625 
∴ Loss = 625 – 616 
= Rs. 9 
Loss percentage =(9/625)×100 
=(900/625)=36/25 
=1 11/25% loss 

S6. Ans.(c)
Sol. Here, purchasing price for mobile phone = Rs. 12000 
Profit percentage = 8% 
∴ Selling price =12000((100 + 8)/100)   
= 12000×(108/100) = Rs. 12960
Again, purchasing price for refrigerator = Rs. 10000 
Loss percentage = 12%
∴ Selling price =10000×((100-12)/100) 
=10000×(88/100) = Rs. 8800 
Now, total SP = 12960 + 8800 
= Rs. 21760 
Total CP = Rs 22000 
∴ Total loss = 22000 – 21760 = Rs. 240  

S7. Ans.(a)
Sol. Here, SP1 = Rs. 1754 ; SP2 = Rs. 1492 
Then, cost price =(SP1 + SP2)/2 
=(1754 + 1492)/2=3246/2   
= Rs. 1623 

S8. Ans.(d)
Sol. Here, cost price of 25 kg of rice 
= 25 × 32 = Rs. 800 
Cost price of 15 kg of rice 
= 15 × 36 = Rs. 540 
Total quantity of rice 
= 25 + 15 = 40 kg 
Total cost of rice = 540 + 800 
= Rs. 1340 
Selling price of rice 
= 40 × 40.20 = Rs. 1608 
∴ Profit = 1608 – 1340 = Rs. 268 
Profit percentage =(268/1340)×100=20%

S9. Ans.(a)
Sol. Let the selling price of each notebook be Rs. 1
Then, selling price of 12 notebooks = Rs. 12 
Profit = Selling price of 4 notebooks = Rs. 4 
Cost price = Selling price – Profit 
= 12 – 4 = Rs. 8 
Profit percentage =(4/8)×100=50%  

S10. Ans.(a)
Sol. Here, selling price of article 
= Rs. 15000
Discount = 10%
Then, selling price 
=15000-(15000×10/100) 
= 15000 – 1500 
= Rs. 13500 
Profit = 8%
Then, cost price = (Selling price × 100)/(100 + Profit%)
=(13500 × 100)/108 
= 125 × 100 = Rs. 12500
