2. Percentage Bar Diagram:

Year Permanent Roads
(Lakh km.)
Percentage of permanent roads Temporary Roads
(Lakh km.)
Percentage of temporary roads
2000-2001 14 = `14 / (14 + 10)` × 100 = `1400 / 24` = 58.33 ≈ 58 10 = `10/ (14 + 10)` × 100 = `1000 / 24` = 41.66 ≈ 42
2001-2002 15 = `15 / (15 + 11)` × 100 = `1500 / 26 ` = 57.69 ≈ 58 11 = `11/ (15 + 11)` × 100 = `1100 / 26` = 42.30 ≈ 42 
2002-2003 17 = `17 / (17+13)` × 100 = `1700 / 30` = 56.66 ≈ 57 13 = `13 / (17 + 13)` × 100 = `1300/30` = 43.33 ≈ 43
2003-2004 20 = `20 / ( 20 + 19)` × 100 = `2000 / 39` = 51.28 ≈ 51 19 = `19/( 20 + 19)` × 100 = `1900/39` = 48.71 ≈ 49
