Direction: The following pie-chart shows the study time of different subjects of a student in a day. Study the pie–chart and answer the following questions
-
The time spent to study history and chemistry is 4 hours 30 minutes, Then the student studied physics for
-
- 1 hour 30 minutes
- 2.9 hours (approx.)
- 2 hours
- 3 hours
Correct Option: D
| Given , Time spent in studying history and chemistry = 4 | hours. | 2 |
As per the given pie chart in question ,
The corresponding percentage of studying physics = 20%
The corresponding percentage of studying history and chemistry = (15 + 15)% = 30%
| ∵ 30% ≡ | hours | 2 |
Now ,
| ∴ 20% ≡ | = 3 hours | 2 × 30 |
