To me, as the previous commenter has mentioned there seems to be an error for the market share calculation for men and teens. For women is correct. For men it should read 24.3

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.
