Which of these denote the condition of neither profit nor loss?
Whenever, Selling Price(S.P.) of an article is more than the Cost Price(C.P.), i.e. S.P.>C.P., then the difference between them(S.P.−C.P.) is the profit.
And, when Cost Price(C.P.) is more than the Selling Price(S.P.), i.e. C.P.>S.P., then the difference (C.P.−S.P.) is the loss.
But, when C.P.=S.P., then there is neither loss nor profit.
In option B, S.P.=Rs. 24004=600 and C.P.=Rs. 720012=600
Since, S.P.=C.P.=Rs. 600, it is a condition of neither profit nor loss.
