Solution

The correct option is C $20$ %
n(Watch new on TV) $= 65 % = n (T)$

n(Reads newspaper) $= 40 % = n (N)$

n(Watch news on TV & read newspapers ) $= 25 % = n (T \cap N)$

$n (N \cup T) = n (T) + n (N) - n (N \cap T)$

$n (N \cup T) = 65 + 40 - 25 = 80 %$
$n (N \cap T)^{c} = 100 - 80 = 20 %$
