Question

In a survey, it was found that 80% of those surveyed owned a car while 60% of those surveyed owned a mobile phone. If 55% owned both a car and a mobile phone, what percent of those surveyed owned a car or a mobile phone or both?

(a) 65% (b) 80% (c) 85% (d) 97.5%

Answer 1

(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%
