Hi,

I'm struggling with questions such as: "Everything constant, by how much % should company X increase sales in Y category (all other categories kept constant) in order to reach the target growth rate. How can I work on such questions or in other words, what topic does this fall under?

Thank you so muchhh

Hello!

I would advise you GMAT quant questions for practicing these type of exercises. You can find many free trials for both exams and exercises in the internet (Veritasprep, London´s Business School MBA´s page, etc.)

However, the way your question is laid, seems more straight forward: for growing by 10%, your sales should grow by 10%, assuming everything else is the same.

Cheers!

Hi Anon,

It sounds like you are struggling to convert word problems into equations - this is pretty essential both in the interview stage of consulting, and on the job as well. It's great that you have identified this as a development need.

I would suggest practicing lots of word problems (e.g. GMAT preparation materials should provide some examples, or the McKinsey PST) and getting comfortable with writing formulas from word problems. There are a few formulas that you could "learn" to help with common types. If you are struggling, have a look at the GMAT solutions - these are usually very clear in terms of method.

As with many quantitative skills, this one gets better with practice!

Best of luck,

Kay

Hi,

This can fall under any category of the case topics. You can give yourself hypothetical examples for you to practice this kind of problems e.g. break-even analysis.

Hi,

Not 100% sure that I understand your question. If you want to grow by 10%, your sales should grow by 10% (assuming everything else is the same)

Hello,

You can practice with questions like these with SHL tests or GMAT.
Btw, the secret is to start from the target: grow revenues by Z%. The next step would be to calculate the absolute value of profit increase, P. Now, you have to achieve this surplus of profits increasing revenues from a specific category, Y. Considering this, your answer is simply P/Y.

I guess that regular quick math practice is as important as p2p case interview sessions.
