Correct option is D)

Given, for the first TV

S.P=Rs2,400 

Profit =20 %

Now, with this S.P. and for Profit % =C.P.S.P.−C.P.×100=20 %

=>C.P.2,400−C.P.×100=20

=>2,400−C.P.=0.20C.P.

1.20C.P.=2,400

=>C.P.=Rs2,000

And for another TV, 

S.P=Rs2,400 

Loss =20 %

So, Loss % =C.P.C.P.−S.P.×100=20

=>C.PC.P.−2,400×100=20

=>C.P.−2,400=0.20C.P.

=>0.8C.P=2,400

=>C.P.=Rs3,000

Total C.P. of both TVs = Rs2,000+Rs3,000=Rs5,000

And Total S.P. =Rs2,400+Rs2,400=Rs4,800

Since Total S.P. < Total C.P.  there will be a loss

And Loss % =
