Answer 1

Given:

The total number of students is 300.

The number of girls is,

48+105=153

The number of students who prefer watching tv is,

105+69=174

(a) To find the percentage of the students who are girls:

The formula is,

`\begin{gathered} \frac{\text{Number of girls}}{\text{Total number of students}}*100\text{ \%}=(153)/(300)*100 \\ =51\text{ \%} \end{gathered}`

Thus, the percentage of the students who are girls is 51%.

b) To find the percentage of students who prefer watching tv:

The formula is,

`\begin{gathered} \frac{\text{Number of students who prefer watch}ing\text{ tv}}{\text{Total number of students}}*100\text{ \%}=(174)/(300)*100 \\ =58\text{ \%} \end{gathered}`

Thus, the percentage of students who prefer watching tv is 58%.
