Ans.
total number of peoples=1200
people who know English language = 800
people who know Punjabi language= 50
Rest of peoples knowing both languages = people who knows English+people who knows Punjabi - total number of peoples..
rest peoples= 1200 - (800+50)
= 350
% of the rest peoples = 350/1200*100
=29.16 %
