ANSWER:

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

2005-2006 47 =47(47+9)×100=470056=83.92≈84 9 =9(47+9)×100=90056=16.07≈16

2007-2008 56 =56(56+13)×100=560069=81.15≈81 13 =13(56+13)×100=130069=18.84≈19

2008-2009 60 =60(60+16)×100=600076=78.94≈79 16 =16(60+16)×100=160076=21.05≈21

2009-2010 63 =63(63+18)×100=630081=77.77≈78 18 =18(63+18)×100=180081=22.22≈22

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