In a survey of 300 people, it was found that 150 people like iPhones and 200 people like Android phones. But 25 people did not like any of these two phones.

1. If I and A denote the sets of people who like iPhone and Android Phones respectively, write the cardinality of $\rm n \overline {( I \cup A ) }$.
2. Present the above information in a Venn diagram.
3. Find the number of people who like iPhones only.
4. Compare the number of people who like both iPhone and Android phones and who do not like any of these two phones.
