Answer 2

Solution:-

given by:-

the people can speak tamil = n(T) = 85%

people can speak English = n(E) = 40%

people can speak HINDI = n(H) = 20%

people can speak both English and Tamil
= n( E∩T) = 32%

people can speak both Tamil and Hindi
= n(T∩H) = (13%)

people can speak both English and hindi
= n( E∩H) = 10%.


the people can speak all the tree languages
= n(T∩E∩H)


n(T∩E∩H) = 100-85-40-20+32+13+10


n(T∩E∩H) = 10


the people can speak all the tree languages 10%
