Answer 1

Answer:

$.$

Step-by-step explanation:

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.

Answer 2

Answer2.5% profit

Step-by-step explanation:

SP of cycle =

(10000-SP/10000)*100=55

SP OF CYCLE =9500

SP OF PHONE=

(SP-10000/10000)*100=10

SP OF PHONE=11000

TOTAL CP=20000

TOTAL SP=20500

(TOTALSP-TOTALCP/ TOTAL CP)*100=

500/20000*100=

5/200*100=

5/2=

2.5%
