Answer 1

Answer:

ANSWER

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.P

C.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 % =

C.P.

C.P.−S.P.

×100=

5,000

5,000−4,800

×100=4 %
