## Table chart

#### Data : -

When we collect information related to different types of facts, then these collected information is called data . The value of the information of these facts is numerically and it is only denoted in the numbers form.

#### Tabulation: -

When we organize the data related to any fact in the columns and rows in sequential order, then the table formed by them is called tabulation. It is the systematic and scientific presentation of numerical data. It helps the person to make comparisons and draw quick conclusions. we read the related data carefully and to give an accurate answer. In this, questions related to various types of problems such as average, percentage, ratio etc are asked.It is very important to have basic knowledge about these chapters, with the help of which we can easily answer the questions asked in tabulation.Tabular presentation makes complicated information easier to understand. In a table, data is arranged systematically in columns and rows.

Let us consider we can understand it with the help of the following given examples.

**Example 1. Direction :** Study the following table to answer the given questions.

(**i**) Which centre has the higher number of candidates?

**Sol **:- As per the above given table ,

Number of candidates :

Delhi → 15000 + 17000 + 160 + 11000 + 750 = 43910

Hyderabad → 3500 + 20000 + 300 + 9000 + 1150 = 33950

Katakana → 14900 + 17650 + 70 + 1300 + 1200 = 35120

Mumbai → 17000 + 19500 + 70 + 7000 + 900 = **44470**

Hence, **Mumbai** has the highest number of candidates.

(**ii**) What is the difference between total number of officers and clerks?** Sol** :- From the above given table ,

Total number of officers = 2000 + 15000 + 17000 + 3500 + 14900 + 11360 + 9000 = 72760

Total number of clerk = 5000 + 17000 + 19500 + 20000 + 17650 + 15300 + 11000 = 105450

Their difference = 105450 - 72760 = **32690**

**Company A** → 110 + 118 +143 + 126 + 152 + 195 = 844

**Company B** → Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )

**Company B** → 91 + 93 + 85 + 99 + 69 + 35 = 472

**Company C** → Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )

**Company C** → 103 + 153 + 100 + 128 + 96 + 56 = 636

**Company D** → Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )

**Company D** → 112 + 166 + 78 + 83 + 135 + 198 = 772

**Company E** → Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )

**Company E** → 72 + 169 + 154 + 98 + 140 + 192 = 825

**Company F** → Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )

**Company F** → 64 + 56 +120 + 70 + 176 + 54 = 540

Hence, **company B** has sold the minimum number of units over the years.

(**ii**) What is the average number of units sold (in crores) in the year **2007**?

**Sol** :- From the above given table ,

In 2007 , the average number of units sold (in crores)

= | ||

Total number of companies |

= | = | = 128 | ||

6 | 6 |

(**iii**) What is the difference between number of units (in crores) sold by company **D** in the year **2003** and the year **2005**?

**Sol** :- On the basis of above given table ,

Required difference = Number of units ( In 2003 - In 2005 )

Required difference = 112 - 78 = **34 crores**

(**iv**) Number of unit sold by company **B** in the year **2005** is what percent of the total number of units sold by all the companies together in the year?

**Sol **:- From the above given table ,

In 2005, total number of units sold by all the companies = Total number of units sold by ( Company A + Company B + Company C + Company D + Company E + Company F )

In 2005, total number of units sold by all the companies = 143 + 85 + 100 + 78 + 154 + 120 = 680

Required percentage = | × 100 | |

Total number of units sold by all the companies in 2005 |

Hence, required percentage = | × 100 = 12.5% | |

680 |

(**v**) Which company has sold the maximum number of units over the years ?** Sol** :- From the above given table ,

Total number of units sold by company A over the years = 110 + 118 + 143 + 126 + 152 + 195 = 844

Total number of units sold by company D over the years = 112 + 166 + 78 + 83 + 135 + 198 = 772

Total number of units sold by company E over the years = 72 + 169 + 154 + 98 + 140 + 192 = 825

Hence, company **A** has sold the maximum number of units over the years.

**Example 3.** Direction: Study the following table and answer the question given below:

(**i**) If 60% boys and 70% girls pass in their respective courses, then total pass percentage is :

**Sol** :- Given in the above table,

∵ Total boys = 45 + 186 +120 +100 + 65 + 32 + 58 + 5 = 611

∴ Number of boys who pass in their respective courses = 60% of 611 =

= 611 x | = 366.60 | |

100 |

Number of girls who pass in their respective courses = 70% of 145

= 145 x | = 101.50 | |

100 |

∴ Combined pass percent = 100 x | = | = 61.92 = 62% | ||

(611 + 145) | 756 |

(**ii**) Total number of boys studying in the college exceeds the total number of girls in the college by:

**Sol** :- As per the above given table , we can see that

Total number of boys = 45 + 65 + 186 + 32 + 120 + 58 + 100 + 5 = 611

Total number of girls = 25 + 23 + 25 + 12 + 25 + 20 + 12 + 3 = 145

∴ Required percentage = | x 100 ≈ 321% | |

145 |

(**iii**) In the art faculty number of students who have opted the course of stenography is how much percent of the total student in the faculty?

**Sol** :- As per the above given table , we have

Percentage of girls in typewriting course = | x 100 = 16.47 | |

261 |

Percentage of girls in stenography course = | x 100 = 12.56 | |

215 |

And percentage of girls in typewriting and stenography course = | x 100 = 12.50 | |

120 |
