At a well known university, 1/4 of the undergraduate students commute and 1/3 of the graduate student commute. One-tenth of the undergraduate student drive more than 40 miles daily and 1/6 graduate students drive more than 40 miles daily. If there are twice as many undergraduate students as there are graduate students then what fraction of the commuters drive more than 40 miles daily.
