1. Draw the graph of the linear equation 3x + 4y
2. Ajay sold two music players for 7500 each. He sold the first at a profit of 10% and the second
at a loss of 10%. Calculate his overall gain or loss percent on the whole transaction.​

Answer 1

Cost price of a T.V set =Rs 10000

profit =10%

Selling price =[100+p/100]×C.P

=[100+10/100]×10000

=110/100×10000

=11×1000

=Rs. 11000

Loss =10%

Selling price =[100−L/100]×C.P

=100−10/100×10000

=90/100×10000

=9×1000

=9000

Total cost price =10000+10000 =20000

Total selling price =11000+9000=20000

Here C.P=S.P

Therefore, it is neither Loss nor Profit.
