There are many formulas for it...Just by applying them and evaluating the values in the formulas you can solve.

For reference, I have put two questions here, which I made.

LOSSES

1. A man sold a bike for Rs.45,000. If he bought it for Rs.35,000, what has he incurred? Profit or Loss? How much?

Answer:
Ok, the SP=45000
the CP=35,000

SP>CP. Note this: whenever the SP or Selling Price is smaller than CP, it is always a Loss.

The formula for finding Basic Loss is L=SP-CP.
In this case:

Loss=45,000-35,000=10,000.

Therefore, the loss=Rs.10,000

Note this:(Loss is called so because if you sold it at the same price, no money is lost. But when you sell it at a smaller price when you could have done it at a higher price, you incurr a loss.

PROFITS
2. Mrs. Khanna bought a Car for Rs.200,000. She sold it on OLX for 350,000. What has she incurred and how much?

Answer:
Ok, It was bought for 200,000 and sold for 350,000.

SP>CP. Note this: whenever SP is greater, it is a profit.

P=SP-CP

350,000-200,000=150,000

Therefore Profit is 150,000.
