Answer 1

Answer: Let the total number of people be 100.  

Let circle A represent people who watch television and B represent people who read newspaper.

Then, x+y=65, y+z=40 and  y=25

We get x=40 and z=15.

Then, the number of people who neither watched television nor read newspaper

=100−(x+y+z)

=100−(40+25+15)

=100−80=20

Therefore, the required percentage is 20%

Answer 2

Step-by-step explanation:

Let the total number of people be 100.

Let circle A represent people who watch television and B represent people who read newspaper.

Then, x+y=65, y+z=40 and y=25

We get x=40 and z=15.

Then, the number of people who neither watched television nor read newspaper

=100−(x+y+z)

=100−(40+25+15)

=100−80=20

Therefore, the required percentage is 20%.
