A class has less than 30 students.
- Exactly 3/4 of them own footballs.
Exactly 7/8 of them own football boots.
i.How many students are there in the class?
ii.How many students own both football boots and footballs?
Take the number of students as $x<30$ and take $y$ as the number of students with both football and football boots, then form your equations
Solve the last equation for non negative integer values of $x$ and $y$ less than $30$
