1. 3.5%
2. 2.5%
3. 3%
4. 2%
=>(1/4) * 600 * (80/100) = Rs. 120
Price Received by remaining material at a gain of 10%
=>(3/4) * 600 * (110/100) = Rs. 495
Total selling price=120+495=615
profit=615-600=15
profit %age=(15/600)*100=5/2=2.5%
=>2.5%
1. 12.5%
2. 12%
3. 14%
4. 11.66%
CP pf 1 pencil=16/9
SP of 1 pencil=22/11=2
Profit=2-(16/9)=2/9
Profit %age=((2/9)/(16/9))*100
Profit %age=12.5
1. 8
2. 6
3. 5
4. 4
Reduced Price of one pen=(10% of 540)/9
=>54/9
=> Rs. 6
1. 10% gain
2. 1% loss
3. No loss or no gain
4. 1% gain
Total SP=110% of 300 + 90% of 300
=>330+270=600
CP=SP
Therefore, No profit No loss
1.Rs. 15
2.Rs. 15.70
3.Rs. 19.70

Therefore 6% of x=30/100
=>x=(30/100)*(100/6)=5
Cost of tax free item=(25-5)-.30= Rs 19.70
