1. The monthly income of a family is â‚¹28800. The monthly expenditure of the family on various items is given below.

 Items Rent Food Clothing Education Savings Expenditure (in â‚¹) 8000 10800 5600 3600 800

Represent the above data by a pie chart.
Solution: We know that the,
Total monthly income = â‚¹28800
By using the formula,
Central angle of component = ((value of the component)/Total value) Ã— 360o
So, the Calculations are

 Items Expenditure(in â‚¹ ) Central angle Rent 8000 (8000/28800) Ã— 360o = 100o Food 10800 (10800/28800) Ã— 360o = 135o Clothing 5600 (5600/28800) Ã— 360o = 70o Education 3600 (3600/28800) Ã— 360o = 45o Savings 800 (800/28800) Ã— 360o = 10o

âˆ´ We can represent the above data in pie chart as shown below:

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) Ã— 360o
So, the Calculations are

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

âˆ´ We can represent the above data in pie chart as shown below:

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) Ã— 360o
So, the Calculations are

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

âˆ´ We can represent the above data in pie chart as shown below:

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) Ã— 360o
So, the Calculations are

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

âˆ´ We can represent the above data in pie chart as shown below:

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) Ã— 360o
So, the Calculations are

 Religion Number of workers Central angle Hindu 450 (450/1080) Ã— 360o = 150o Muslim 270 (270/1080) Ã— 360o = 90o Sikh 255 (255/1080) Ã— 360o = 85o Christian 105 (105/1080) Ã— 360o = 35o

âˆ´ We can represent the above data in pie chart as shown below:
