(iii) English newspapers only.

Answer 1

let no of tamil newspapers is x
no of English newspapers is y

so 65+55=120
now 120-100 = no of families read both newspapers
120-100=20 families read both languages papers

now 65-20=45
& 55-20=35

now confirm 45+35=80 so add 80 and 20 u get 100

so ans
eng families=45
tam families=35
both reading=20
and =100
