S/T = 80/3

Given T = 5, S = (80/3) * 5 ~ 133 D

T/S > 3/80
if T = 5 then S should be less than 80*5/3 = 133.3 = 133 (since number of students is +ve integer).

Private tutor exclusively for the GMAT and GRE, with over 20 years of experience.
Followed here and elsewhere by over 1900 test-takers.
I have worked with students based in the US, Australia, Taiwan, China, Tajikistan, Kuwait, Saudi Arabia -- a long list of countries.
My students have been admitted to HBS, CBS, Tuck, Yale, Stern, Fuqua -- a long list of top programs.

As a tutor, I don't simply teach you how I would approach problems.
I unlock the best way for YOU to solve problems.
