Question

Study the pie chart and information given and answer the following question:
There are $1150$ students of a school who opted sports as a hobby.
How many students have book reading as a hobby?

• A. $390$
• B. $420$
• C. $440$
• D. $450$

Answer 1

The correct option is D $450$

23% of total students opted sports as a hobby

Let total number of students be $x$

$0.23x$$=1150$

$\frac{23}{100}x=1150$

So, $x=5000$

9% of $x$ opted book reading as a hobby,

$0.09\times 5000$

$\frac{9}{100}\times 5000=450$

Hence, Option D is correct answer.
