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 % =
Loss = Rs. 120. loss % = 1%
B
Loss = Rs. 150. loss % = 2%
C
Loss = Rs. 190. loss % = 3%
D
Loss = Rs. 200. loss % = 4%
