I think...

Using proportions,

3/80 = 5/x

x = (80x5)/3 = 133.333333

Therefore 134?

I also got 134 following the same approach but I was wrong. The correct answer is 133.

Here what I think abt the stmt:

t/s > 3/80

so if the denominator is lesser the value will be bigger...

if 3 teachers, the students < 80
and if 5 teachers, the sts < (80*5)/3 = 133.3

s<133.3 means answer is 133, not 134.

Am I doing it right?

I think this is a GMATPrep question.

Please prefix with GMATPrep in subject line so that people who did not take the GMATPrep test would not know about it until they take the practise test

Thanks! :)
