What is the percentage share of 'School time' in the given pie-chart?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 25%
The pie chart divides one whole day of 24 hours among the activities, and the size of each slice follows its hours. So the share of an activity is its hours divided by the total hours, turned into a percentage.
Total of the hours shown: \(8+4+3+3+6=24\) hours (sleep, homework, others, play, school)
Share of school time \(\displaystyle =\frac{6}{24}\times100=25\%\)
