**OBJECTIVE QUESTIONS :**

**Tick the correct answer in each of the following:**

**Question 1.**

**A man’s monthly salary is Rs. 2400 and his monthly expenses on travel are Rs. 250. The central angle of the sector representing travel expenses in the pie chart would be**

**(a) 30°**

**(b) \(37{ \frac { 1 }{ 2 } }^{ o } \)**

**(c) 45°**

**(d) 60°**

**Solution:**

Answer = (b)

Central angles = \(\\ \frac { 250 }{ 2400 } \) x 360°

= \(\\ \frac { 75 }{ 2 } \)

= \(37{ \frac { 1 }{ 2 } }^{ o } \)

**Question 2.**

**If 35% of the people residing in a locality are Sikhs then the central angle of the sector representing the Sikh community in the pie-chart would be**

**(a) 108°**

**(b) 115°**

**(c) 126°**

**(d) 135°**

**Solution:**

Answer (c)

Central angle = \(\\ \frac { 35 }{ 100 } \) x 360°

= 126°

**Question 3.**

**If in the pie chart representing the number of students opting for different streams of study out of a total strength of 1650 students, the central angle of the sector representing Arts students is 48°, what is the number of students who opted for Arts stream ?**

**(a) 220**

**(b) 240**

**(c) 275**

**(d) 320**

**Solution:**

Answer = (a)

Total number of strength = 1650

Arts stream’s central angle = 48°

No. of students of Arts stream

= \(\\ \frac { 48 }{ 360 } \) x 1650

= 220

**Question 4.**

**In the pie chart representing the percentages of students having interest in reading various kinds of books, the central angle of the sector representing students reading novels is 81°. What is the percentage of students interested in reading novels ?**

**(a) 15%**

**(b) 18%**

**(c) \(22{ \frac { 1 }{ 2 } } \)%**

**(d) \(27{ \frac { 1 }{ 2 } } \)%**

**Solution:**

Answer = (c)

Central angle of students reading novels = 81°

\(\\ \frac { 81 }{ 360 } \) x 100

= \(\\ \frac { 45 }{ 2 } \)

= \(22{ \frac { 1 }{ 2 } } \)%
