Answer:
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.
