# How many dentists are in your country?

One of the questions I had today:

• How many dentist are in your country?

How would you solve this question?

One of the questions I had today:

• How many dentist are in your country?

How would you solve this question?

• Date ascending
• Date descending

Classic type of case here :)

1. Population of country
2. Split by income/wealth level (poor, middle, upper class)
3. Estimate # of visits per year per group (of course, directly correlated with socioeconimic status...benchmark off of how often you go)
4. # of visits a dentist probably has per day (do not assume full capacity)
5. # days/weeks worked per dentist
6. Divide Q3xQ2 by Q4xQ5
7. Multiply by a factor of your choice to account for doctor holidays/days off and/or non-full capacity at doctor's offices

And voila!

Bread-and-butter type of case here!

Almost made the same approach, except I divided per age category (children, mature, old). — Anonymous A on Feb 02, 2021

So, here's the question...which one is more directly correlated with frequency of visits? I would argue, regardless of age, you'll go to the dentist around once ayear. But, if you're poorer you can't afford to go as frquently (or at all). Remember...they're not testing just the final #...they're testing for your reasoning. Pick the categories that increase/decrease frequency the most! — Ian on Feb 04, 2021

Hi, in addition to the solutions proposed by the other coaches in the discussion, I would like to suggest similar cases in the platform to practice with:

Hi there,

Ian is spot on! Besides, it really makes sense how you reason it and not necessarily if that is the most correct answer.

There are a lot of questions on market sizing on Preplounge, and it is a nice practice!

Hello!

This is a very classic type of market sizing.

I would suggest:

• Population
• Break it down in age buckets -you could also do economic level, but this one for me is more powerful-.
• Calculate number of visits per group
• Calculate how many appointments one dentist can make

Hope it helps!

Cheers,

Clara

### Bain Case: Old Winery

Solved 71.9k times
Bain Case: Old Winery You have inherited the “Old Winery” from your grandfather, a winery that has been family-owned for five generations and can be dated back to the 16th century. Half of the eleven hectares are used to grow white grapes, the other half to grow red grapes. They are grown in a conventional way, i.e. they are not organically farmed and certified. The vine stocks are in a good condition regarding age and care. Overall, the only ¼ of the harvest is made into wine by the winery itself; the rest is sold. Your grandfather never wanted to change the image of the winery and left the managerial and administrative task to a young and energetic wine-maker. Due to the not so well-known brand, the demand for the “Old Winery” wine is currently rather low. You do not intent to run the winery operatively, given your limited knowledge of winemaking, but find the idea of owning a winery exciting. Your plan is to give the winery some fresh impetus.

### Roland Berger Case: Onlinestar

Solved 51.3k times
Roland Berger Case: Onlinestar Onlinestar, an online retailer of furniture and garden products (core business), has grown significantly in recent years as a result of an expansion of its product portfolio. The company mainly imports goods from Chinese manufacturers but also operates its own production of cat lavatories (special business) in Eastern Europe. The company sells its goods via Amazon and eBay, and recently via an online shop on its website. Despite this development, the financial ratios have deteriorated in recent years. In particular, the gross profit margin decreased significantly. Combined with a significant increase in shipping costs, this led to a negative result for the first time in the recently ended fiscal year and a resulting strained financial situation. Against the background of expected stagnating sales for the current financial year, short-term action is required. The board of Onlinestar asks you for an analysis of the reasons for the negative result as well as a derived recommendation for action. As a consultant, you should bring in your knowledge in online trading and develop solutions. In addition, the management board would like to receive a sales and gross profit plan from you for the current financial year.

### Children vaccine

Children vaccine Beyer, one of the biggest pharmaceutical companies in the world, just invented a very reliable vaccine against Chickenpox, a disease that affects children in the age from 2 to 16 years. Beyer came to you wondering what their potential sales in Europe in the first year would be if they launched this product next year. They are only interested in the overall sales revenue as they already know that the vaccine can be sold for a profit.
