Question Nov.25th

by bacali » Tue Nov 25, 2008 8:04 am
In a survey of 200 college graduates, 30 percent said they had received student loans during their college careers, and 40 percent said they had received scholarships. What percent of those surveyed said that they had received neither student loans nor scholarships during their college careers?

(1) 25 percent of those surveyed said that they had received scholarships but no loans.
(2) 50 percent of those surveyed who said that they had received loans also said that they had received scholarships.

A tabular approach is best here:
These values are given in the question stem
--------------S--------------NS------------Total
----L--------30 --------------------------- 60
----NL-------50-------------?--------------
Total--------80-------------------------------200

Now, according to stmt 1,
25%(200) = 50 have recieved scholarships but no loans...(in green)
fill values.

According to stmt 2,
50%(60) = 30 ( in red)

hence both are suff since we want to find the value of '?'
Hope it explains clearly....
What if i have not yet beat the beast, I know i will beat it!!!!!!!!
