5. Profit %=((SP-CP)/CP)*100
6. Loss %=((CP-SP)/CP)*100
7. CP=100 SP/(100+Profit%)
8. CP=100 SP/(100-Loss%)
9. SP=(100+Profit%) CP/100
10. SP=(100-Loss%) CP/100
11. Two successive discounts of d₁% and d₂% is equivalent to a single discount of d₁+d₂-(d₁d₂/100).
12. Three successive discounts of d₁% , d₂% and d₃% is equivalent to a single discount of d₁+d₂+d₃-(d₁d₂/100)-(d₂d₃/100)-(d₃d₁/100)+(d₁d₂d₃/10000).
13. When two same items are sold, one at a profit of x% and the other at a loss of x%. Then the transaction incurs a loss %=(x/10)².
14. If false weight is used then profit %=(error/(true value - error))*100.
15. Two successive profits of p₁% and p₂% results in a total profit %=p₁+p₂+(p₁p₂/100)
16. If an item is marked p% above its Costprice and a discount of l% is allowed on the marked price then profit/loss %=p-l-(pl/100)
