Solution
Given Jeff has 40 US and 50 British stamps. All US stamps are valuable and half of British stamps are valuable. Also given total valuable stamps are three times that of US stamps.
So, total valuable stamps=40+(50/2)+x=3*40
40+25+x=120
x=120-65=55
So, the valuable stamps that are neither US or british stamps are 55/
