How to solve profit & loss sums

Hi Sushma
Profit and loss sums are fairly simple and are generally based on the simple application of formula.
There are various variants for questions, so you could post an example, I can help you better.
Some formulae which are useful are
Profit = SP - CP
Loss = CP -SP
Profit % = Profit*100/CP
Loss = Loss*100/CP
Thanks.
