__Exercise 24A__

**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— 360^{o}

So, the Calculations are

Items | Expenditure(in â‚¹ ) | Central angle |

Rent | 8000 | (8000/28800) Ã— 360^{o} = 100^{o} |

Food | 10800 | (10800/28800) Ã— 360^{o} = 135^{o} |

Clothing | 5600 | (5600/28800) Ã— 360^{o} = 70^{o} |

Education | 3600 | (3600/28800) Ã— 360^{o} = 45^{o} |

Savings | 800 | (800/28800) Ã— 360^{o} = 10^{o} |

âˆ´ 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) Ã— 360^{o}

So, the Calculations are

Animals | Number of animals | Central angle |

Beast animals | 150 | (150/900) Ã— 360^{o} = 60^{o} |

Other land animals | 400 | (400/900) Ã— 360^{o} = 160^{o} |

Birds | 175 | (175/900) Ã— 360^{o} = 70^{o} |

Water animals | 125 | (125/900) Ã— 360^{o} = 50^{o} |

Reptiles | 50 | (50/900) Ã— 360^{o} = 20^{o} |

âˆ´ 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) Ã— 360^{o}

So, the Calculations are

Mode of transport | Number of students | Central angle |

School bus | 350 | (350/1260) Ã— 360^{o} = 100^{o} |

Private bus | 245 | (245/1260) Ã— 360^{o} = 70^{o} |

Bicycle | 210 | (210/1260) Ã— 360^{o} = 60^{o} |

Rickshaw | 175 | (175/1260) Ã— 360^{o} = 50^{o} |

On foot | 280 | (280/1260) Ã— 360^{o} = 80^{o} |

âˆ´ 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) Ã— 360^{o}

So, the Calculations are

Activity | Number of hours | Central angle |

School | 7 | (7/24) Ã— 360^{o} = 105^{o} |

Homework | 4 | (4/24) Ã— 360^{o} = 60^{o} |

Play | 2 | (2/24) Ã— 360^{o} = 30^{o} |

Sleep | 8 | (8/24) Ã— 360^{o} = 120^{o} |

Others | 3 | (3/24) Ã— 360^{o} = 45^{o} |

âˆ´ 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) Ã— 360^{o}

So, the Calculations are

Religion | Number of workers | Central angle |

Hindu | 450 | (450/1080) Ã— 360^{o} = 150^{o} |

Muslim | 270 | (270/1080) Ã— 360^{o} = 90^{o} |

sikh | 255 | (255/1080) Ã— 360^{o} = 80^{o} |

Christian | 105 | (105/1080) Ã— 360^{o} = 35^{o} |

âˆ´ we can represent the above data in pie chart as:

**Exercise 24B**

**OBJECTIVE QUESTIONS**

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

**1. A manâ€™s monthly salary is â‚¹24000 and his monthly expenses on travel are â‚¹2500. The central angle of the sector representing travel expenses in the pie chart would be**

**30**^{o}**37 Â½**^{o}**45**^{o}**60**^{o}

Solution: We know that the monthly salary = â‚¹24000

Monthly expense on travel = â‚¹2500

By using the formula,

Central angle of component = ((value of the component)/Total value) Ã— 360^{o}

= (2500 / 24000) Ã— 360^{o}

= 37.5^{o} = 37 Â½^{ o}

**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**

**108**^{o}**115**^{o}**126**^{o}**135**^{o}

Solution: We know that the total people residing in locality = 100 %

Sikh people residing in the same locality = 35%

By using the formula,

Central angle of component = ((value of the component)/Total value) Ã— 360^{o}

= (35 / 100) Ã— 360^{o}

= 126^{o}
