Answer:
Given, for first TV
S.P=Rs6,900
Profit =15 %
Now, with this S.P. and for Profit % =C.P.S.P.−C.P.×100=15 %
=>C.P.6,900−C.P.×100=15
=>6,900−C.P.=0.15C.P.
1.15C.P.=6,900
=>C.P.=Rs6,000
And for another TV,
Loss =10 %
So, Loss % =C.P.C.P.−S.P.×100=10
=>C.PC.P.−S.P.×100=10
=>C.P.−S.P.=0.10C.P.
=>0.9C.P=S.P. --- (1)
Given, There is no profit or loss in the whole transaction
=>TotalS.P.=TotalC.P.
=>6,900+S.P.=6,000+C.P.
=>S.P.+900=C.P. --- (2)
From equations 1 , 2
=>0.9C.P+900=C.P.
=>0.1C.P.=
