1. The monthly income of a family is ₹28800. The monthly expenditure of the family on various items is given below.

Items Rent Food Clothing Education Savings
Expenditure
(in ₹)
8000 10800 5600 3600 800

Represent the above data by a pie chart.
Solution: We know that the,
Total monthly income = ₹28800
By using the formula,
Central angle of component = ((value of the component)/Total value) × 360o
So, the Calculations are

Items Expenditure(in ₹ ) Central angle
Rent 8000 (8000/28800) × 360o = 100o
Food 10800 (10800/28800) × 360o = 135o
Clothing 5600 (5600/28800) × 360o = 70o
Education 3600 (3600/28800) × 360o = 45o
Savings 800 (800/28800) × 360o = 10o

∴ we can represent the above data in pie chart as:

2. There are 900 creatures in a zoo as per list given below:

Beast animals Other land animals Birds Water animals Reptiles
150 400 175 125 50

Represent the above data by a pie chart.
Solution: We know that the,
Total animals =900
By using the formula,
Central angle of component = ((value of the component)/Total value) × 360o
So, the Calculations are

Animals Number of animals Central angle
Beast animals 150 (150/900) × 360o = 60o
Other land animals 400 (400/900) × 360o = 160o
Birds 175 (175/900) × 360o = 70o
Water animals 125 (125/900) × 360o = 50o
Reptiles 50 (50/900) × 360o = 20o

∴ we can represent the above data in pie chart as:

3. Various modes of transport used by 1260 students in a given school are given below:

School bus Private bus Bicycle Rickshaw On foot
350 245 210 175 280

Represent the above data by a pie chart.
Solution: We know that the,
Total students =1260
By using the formula,
Central angle of component = ((value of the component)/Total value) × 360o
So, the Calculations are

Mode of transport Number of students Central angle
School bus 350 (350/1260) × 360o = 100o
Private bus 245 (245/1260) × 360o = 70o
Bicycle 210 (210/1260) × 360o = 60o
Rickshaw 175 (175/1260) × 360o = 50o
On foot 280 (280/1260) × 360o = 80o

∴ we can represent the above data in pie chart as:

4. The data given below shows number of hours spent by a school boy on different activities on a working day.

Activity School Homework Play Sleep Others Total
Number of hours 7 4 2 8 3 24

Represent the above data by a pie chart.
Solution: We know that the,
Total number of hours =24
By using the formula,
Central angle of component = ((value of the component)/Total value) × 360o
So, the Calculations are

Activity Number of hours Central angle
School 7 (7/24) × 360o = 105o
Homework 4 (4/24) × 360o = 60o
Play 2 (2/24) × 360o = 30o
Sleep 8 (8/24) × 360o = 120o
Others 3 (3/24) × 360o = 45o

∴ we can represent the above data in pie chart as:

5. The data on religion wise division of 1080 workers of a factory are given below:

Religion Hindu Muslim Sikh Christian
Number of workers 450 270 255 105

Represent the above data by a pie chart.
Solution: We know that the,
Total number of workers =1080
By using the formula,
Central angle of component = ((value of the component)/Total value) × 360o
So, the Calculations are

Religion Number of workers Central angle
Hindu 450 (450/1080) × 360o = 150o
Muslim 270 (270/1080) × 360o = 90o
sikh 255 (255/1080) × 360o = 80o
Christian 105 (105/1080) × 360o = 35o

∴ we can represent the above data in pie chart as:
