Answer 1

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:
