U=400 Let S be the set of spaniel speakers Let E be the set of English speakers : as we know universal set (U)= 400 : also, S +E that is 250+200=450 Therefore, 450-400 =50 people must speak both languages. Because universal set is the sum of all the sets but the sum of both sets is greater than the universal set i.e 450>400,this shows that 50 peoples must speak both languages

Ans. Let S be the set of people speaking Spanishand E be the set of people speaking English. n(S)=250 n(E)=200 n(S Union E)=400 n(S Union E) = n(S) +n(E)- n(S intersection E) 400=250+200 - n(S intersection E) 400=450- n(S intersection E) 400-450=n(S intersection E) n(S intersection E)=50
