Help with Case Interview [#permalink] New post 17 Apr 2014, 09:22

I am going through the first case interview in the "vault case interview practice guide 2."

A copy of it is here: sites . duke . edu / dukeapdconsulting / files / 2010 / 08 / Vault_Guide 2008 . pdf

(I have to space it out, or else the website won't let me post it) However, I have also attached a pdf here.

The case study is entitled "Amusement Park Case," and is pg. 19 through 24.

I am having issues with the last page, pg. 24.

Two issues:

1. I don't understand how the Revenue values are calculated (e.g., 12.775M, 10.9M, 10M), because the values reflected are different on the previous page. I also tried to include the revenue from non-ticket revenue, but I still didn't get the correct values.

2. I do not understand why the recommendation is C. From the final calculation, it seems that C is the least profitable.

Any help would be appreciated. Let me know if I need to provide more clarification.

I didn't do the calculation, but are you factoring in the non-ticket (concessions) revenue? The case doesn't show the calc, but does provide the data.

Hi! I calculated all the values and clearly A is the winner, my methodology is in accordance with their calculations, but they clearly have a lot of mistakes. For example A is shown to have 39% + 50% + 20%=109% (!), though in calculation it's corrected to 100%.
There are many other mistakes in rev. calculations, inlcuding 150*,3 = 50 (!). I wouldn't trust that guide. Maybe that's an excercise to identify mistakes? There are too many to be real.

Even then, they have highest GM in A, but still recommended C ??? very strange indeed.

Stay positive! ^.^
