(c) Percentage of car owners = 80%

Percentage of mobile phone owners = 60%

Percentage having both car and mobile phone = 55%

Percentage of having only car = 80 – 55 = 25%

Percentage of having mobile phone = 60 – 55 = 5%

Percentage of having a car or a mobile phone or both

= 55% + 25% + 5%

= 85%
