In a group

Answer :

Let H be the set of people who speak Hindi,


and E be the set of people who speak English.


Number of people who speak Hindi = n(H) = 250


Number of people who speak English = n(E) = 200


Total Number of people = n(H E) = 400


Number of people who can both speak Hindi and English


= n(H E)


We know that-


n(H E) = n(H)+ n(E) - n(H E)


400 = 250+200 - n(H E)


400 = 450 - n(H E)


n(H E) = 450-400


n(H E) = 50


Thus, 50 people can speak both Hindi and English.
