I don't see how it's mathematically impossible. ~115 decided not to go to HBS. If it's true that 35% of those currently attending Stanford, that applied to both schools, also got into HBS (could be wrong, but that's how I interpreted what he said, it's possible he estimated at both schools based on discussions with his counterparts at HBS). So, assume 70% of the students at Stanford applied to both schools, that means 70%*400=280. Then,take 35%*280=98.
So, this assumes that 98 students didn't go to HBS to go to Stanford, and the other 17 didn't go to HBS for other reasons. Maybe you disagree with the assumptions, but it's not impossible.
Prof says 35% of Stanford students got into HBS. WIth 410 in the Class of 2016 class, that would be ~144 students who supposedly got into HBS (410 x 35%). If you look at the HBS numbers, their yield is 89% on a class of 940 would imply a total admitted group of ~1056 (940 / 89%). The difference between those matriculating and the total number of admits is only 116. Therefore it's impossible for 144 Stanford GSB students to get into HBS when only 116 chose not to go.[/quote]
Ah OK, if everyone at Stanford applied to both schools, then you're right - it was 35% of those that applied to both. I figured not everyone applied to both.
