if you are thinking about VERBAL questions with this much precision... you're thinking about them in entirely the wrong way. you will NEVER, EVER need to nit-pick the quantitative aspects of a verbal problem like this.
just remember— THE VERBAL SECTION IS NOT THE QUANT SECTION.
in normal everyday life, people use "many" to mean, basically, "a significant number, but not most". ...so, not vanishingly few, but also not more than 50 percent. but, again, you will NEVER need to think with such precision on the verbal section.
