Question

In the table given below, the information is given about roads. Using this draw sub-divided and percentage bardiagram (Approximate the percentages to the nearest integer)

Year    Permanent Roads 
      ( Lakh km.)
  Temporary Roads 
      ( Lakh km.)
 
2000-2001           14       10
 2001-2002      15    11
   2003-2004    17   13
   2007-2008     20   19

Solution

In the table given below, the information is given about roads.

Year Permanent Roads
(Lakh km.)
Percentage of permanent roads Temporary Roads
(Lakh km.)
Percentage of temporary roads
2000-2001 14 = `14 / ( 14 + 10 )` x 100 = `1400 / 24` = 58.33 ≈ 58 10 = `10/ ( 14 + 10 )` x 100 = `1000 / 24` = 41.66 ≈ 42
2001-2002

15

= `15 / ( 15 + 11 )` x 100 = `1500 / 26 ` = 57.69 ≈ 58 11 = `11/ ( 15 + 11)` x 100 = `1100 / 26` = 42.30 ≈ 42 
2003-2004 17 = `17 / (17+13)` x 100 = `1700 / 30` = 56.66 ≈ 57 13 = `13 / ( 17 + 13 )` x 100 = `1300/30` = 43.33 ≈ 43
2007-2008 20 = `20 / ( 20 + 19)` x 100 = `2000 / 39` = 51.28 ≈ 51 19 = `19/( 20 + 19)` x 100 = `1900/39` = 48.71 ≈ 49

The sub-divided and percentage bar-diagram of the above table is as follows:
