Answer 1

Given:

The given circle graph shows the number of hours a college student spends studying each subject.

To find:

Which subject gets 30% of the students study time?

Solution:

From the given circle graph, we get study time of following subjects:

Art = 10 hr

P.E. = 6 hr

History = 13 hr

English = 5 hr

Math = 9 hr

Total study time is:

$10+6+13+5+9=43\ hr$

30% of 43 hr is:

$43\times \dfrac{30}{100}=12.9$

$43\times \dfrac{30}{100}\approx 13 \hr$

It means 30% of 43 hr is about 13 hr.

Since study time of History is 13 hr, therefore History gets 30% of the students study time.

Hence, the correct option is C.
