The following pie chart shows the study time of different subjects of a student in a day.
If the total time spent to study History and Chemistry is 4 h 30 m, then the student studied Physics for:
Answer & explanation
Correct answer: option 4
The total time spent to study History and Chemistry is 4 h 30 m or = 270 minutes
Let the total time = 100%
History + Chemistry = 15% + 15% = 30%
given time for physica = 20%
So, the student studied the Physics for = \(\frac{270}{30}\) × 20 =
180 minutes or 3 hours
