Answer 2

case-1                                                           case-2

cost price of tv set= 10,000 rs                  cost price of tv set=10,000 rs

                                                                   LOSS%=10%                                                                                                        

profit%=10%                                              sp=(100-L%/100) cp

sp=100+ p%/100*cp                                      =(90/100)10,000

   = (100+10/100)10,000                                   =9000 rs

= (110/100)10,000

=11000rs

total cp= 10,000+ 10,000

                      = rs 20,000

total sp= 11000+9000

            =            20,000

it is neither profit nor loss it is equal
