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=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

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