Error on calculation

Hi Yasmin, 

That's true. 

This happens often in cases, regardless of whether they are from this platform or in case books from top business schools. 

It also resembles what happens in reality. 

Even during the interviews, it's not critical to be 100% accurate. The calculation part of the interview is not testing for accuracy or whether you are a math genius. Instead, it's trying to figure out how well you can communicate and co-create an approach with another person (basically, the client). 

Happy to share with you also a guide - no strings attached - on how to best approach calculation questions. 

Best,
Cristian

Nice catch! Agreed. Remember that most cases have an error or two in them.
