100 is belonging to neither class
yogesh2703:
but how ? 100?
120 belongs to upper class,80 belongs to upper middle class
but 60 belong to both
So, only 60 purely belong to middle class and 20 purely belong to upper middle class
240-(60+60+20)= 100 belongs to neither class
pls mark it as Brainliest
ok thanks!
thanx
