Answer 2

Step-by-step explanation:

In the first transaction,

Profit % =C.PS.P.−C.P.×100

=>C.P.990.−C.P.×100=10

=>990−C.P.=0.1C.P.

=>1.1C.P.=Rs990

−>C.P.=Rs900

Now, at loss 10 % ,

 

Loss % =C.PC.P.−S.P.×100=10

=>990C.P.−990×100=10

=>C.P.−990=99

=>C.P.=990+90=Rs1080

SO, total C.P. =Rs900+Rs1080=Rs1980

total S.P. =Rs990+Rs990=Rs1980

Since, C.P.=S.P, there is no gain or loss

it would be like this
