Answer 2

Given:

Percentage of people using Facebook= 65%

Percentage of people using Whatsapp= 40%

Percentage of people using both= 25%

To find:

Percentage of people using neither Facebook nor Whatsapp

Solution:

Percentage of people using only Facebook= (65-25)% = 40%

Percentage of people using only Whatsapp= (40-25)% = 15%

So, total percentage of people liking something= (40+15+25)% = 80%

So, percentage of people not liking anything= (100-80)% = 20%

Percentage of people using neither Facebook nor Whatsapp is 20%.
