Hi,
May I be assisted with the following please?
1.) A book was sold for $45 at a loss of 10%. What was the original price?
2.) A man bought a chair for $350. He sold it at a profit of 25%. How much was the selling price?
Edit2: This post was editted after I made a mistake.
1) I think 1 is incorrect.
The man sold the book for $45 which was a 10% loss.
This means that he only sold the book at 90% of the original price.
Which means that where is the original price in dollars.
2) Is fine.
