The responses of the students is given in the table below:

(a)The Percentage that are boys

• Number of boys = 81+60=141

,

• The total number of students surveyed = 300

Therefore, the percentage of the students that are boys will be:

`\begin{gathered} (141)/(300)*100 \\ =(141)/(3)\% \\ =47\% \end{gathered}`

47% of the students are boys.

(b)The percentage that prefers playing video game

• The number of students who prefer playing video games = 45+81=126

,

• The total number of students surveyed = 300

Therefore, the percentage that prefers playing video game is:

`\begin{gathered} (126)/(300)*100 \\ =(126)/(3) \\ =42\% \end{gathered}`

42% of the students prefers playing video games.
