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
- Instead of 10%, if the student spends 15% to study other subjects and the time is taken from the time scheduled to study mathematics and if he/she used to study 20 hours per day, then the difference of time for studying mathematics per day is :

On the basis of given pie chart in question ,
Percent of studying Maths students = 30%
Time spent in mathematics in a day = 20 hoursUsual time spent in studying Maths = 2 × 30 = 6 hours 100 Usual time spent in studying other subjects = 10 × 20 = 2 hours 100
Correct Option: C
On the basis of given pie chart in question ,
Percent of studying Maths students = 30%
Time spent in mathematics in a day = 20 hoursUsual time spent in studying Maths = 2 × 30 = 6 hours 100 Usual time spent in studying other subjects = 10 × 20 = 2 hours 100 New time spent in studying other subjects = 15 × 20 = 3 hours 100
Difference = New time spent in studying other subjects - Usual time spent in studying other subjects
Difference = 3 – 2 = 1 hours
- If the student studied 10 hours in a day, then he/she studied mathematics for

As per the given pie chart in question ,
Percent of studying given all subject by students = 100%
Percent of studying mathematics students = 30%
The student studied in a day = 10 hours
∵ 100% ≡ 10 hours∴ 1% = 10 100 Correct Option: A

On the basis of given pie chart in question ,
The student studied chemistry = 3 hours
Percent of studying chemistry students = 15%
Percent of studying geography students = 10%
∵ 15% ≡ 3 hoursCorrect Option: B
On the basis of given pie chart in question ,
The student studied chemistry = 3 hours
Percent of studying chemistry students = 15%
Percent of studying geography students = 10%
∵ 15% ≡ 3 hours∴ 10% ≡ 3 × 10 = 2 hours 15

Given , Time spent in studying history and chemistry = 4 1 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% ≡ 9 hours 2
Correct Option: D
Given , Time spent in studying history and chemistry = 4 1 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% ≡ 9 hours 2
Now ,∴ 20% ≡ 9 × 20 = 3 hours 2 × 30
Direction: The following pie chart shows the export of automobiles of India to the 10 countries given below in 2014. The 10 countries imported 47.8% of the total export of India. Observe the chart given below and answer the following question :

On the basis of given pie chart in question ,
Percent of exports for Turkey = 4%
We know that , 100% ≡ 360°∴ 1% ≡ 360 100
Correct Option: A
On the basis of given pie chart in question ,
Percent of exports for Turkey = 4%
We know that , 100% ≡ 360°∴ 1% ≡ 360 100 ∴ 4% ≡ 360 × 4 = 14.4° 100
