Question

Suhas surveyed the opinions of $50$ students from his class on the impact of social media in their lives, and represented the survey data using the below circle graph.


How many students felt that social media is time-consuming?

• A. $30$
• B. $25$
• C. $21$
• D. None of the above

Answer 1

The correct option is C $21$

Total number of students involved in the survey= $50$

Suhas represented the survey data on the impact of social media in student's life in the form of a circle graph as shown below.



From the above circle graph, it is clear that $42\%$ of $50$ students believe the social media is time-consuming.

$\therefore$ The number of students felt that the social media is time-consuming is
$42\%\text{of}50=\frac{42}{100}\times 50=21$

$\therefore$ Option (c.) is the correct one.
