Altought there are some classic responses here (Interest rates calculations, compound margin, NPV, etc.), truth is that in 99% of the cases is not going to be anything more complicated than break-even analysis.

Hope it helps!

Best,

Hello!

Altought there are some classic responses here (Interest rates calculations, compound margin, NPV, etc.), truth is that in 99% of the cases is not going to be anything more complicated than break-even analysis.

Solving the problems by calculating the area of the triangle

Profit / breakeven formula

Correlations, outliers (being able to spot on the graphs, tables)

2) Fast math skills

Rounding up and down

Learn how to multiply double digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo)

Learn the division table up to 1/11 (i.e. 5/6 = 83.3)

Learn how to work with zeros using powers (e.g.: 4000000 = 4*10ˆ6)

Use math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

3) Working with tables and graphs and deriving conclusions

Study "Say it with Charts" book

Check all available MBB presentations and publications. Practice to derive conclusions and check yourself with the actual ones from the article / presentation

Honestly, you're going to find this for every single question you ask regarding casing. That's because the world of casing is vast! moreso than memorizing everything, you need to learn to react to things you don't know!

That being said, the most common equations are:

NPV - annuity

NPV - perpetuity

Breakeven (across a range of scenarios)

% change

ROI

Margin

Markup

Inventory Turnover

Throughput

2 - Exact formulas

Google is your friend here. Honestly, if you google and research the equations, you're going to learn them much more effectively. We can't just list every formula here for you.

3 - When to use

I'm sorry, but this is also a huge question! We can't really answer this in one go here nor should we. I highly recommend you simply go down the list provided, and test your knowledge of them in cases.

Additionally, hire a coach! 1 session will do wonders in terms of your knowledge of these questions.
