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
