उत्तर
The following table shows the number of Buses and Trucks in nearest lakh units.
| Year | No of trucks | Percentage of trucks | No of buses | Percentage of buses |
| 2006-2007 | 47 | = `47/ ( 47 + 9 )` × 100 = `4700 / 56` = 83. 92 ≈ 84 | 9 | = `9 / ( 47 + 9 )` × 100 = ` 900 / 56 ` = 16.07 ≈ 16 |
| 2007-2008 | 56 | = ` 56/ ( 56 + 13)` × 100 = ` 5600 / 69` = 81.15 ≈ 81 | 13 | = `13 / ( 56 + 13)` × 100 = `1300/69` = 18.84 ≈ 19 |
| 2008-2009 | 60 | = ` 60 / ( 60 + 16 )` × 100 = `6000 / 76` = 78.94 ≈ 79 | 16 | = ` 16 / ( 60+ 16 )` × 100 = `1600 / 76` = 21.05 ≈ 21 |
| 2009-2010 | 63 | = `63 / ( 63 + 18 )` × 100 = `6300/ 81`= 77.77 ≈ 78 | 18 | = `18 / ( 63 + 18 )` × 100 = `1800 / 81 ` = 22.22 ≈ 22 |
