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	$=\frac{47}{\left(47+9\right)}\times 100=\frac{4700}{56}=83.92\approx 84$	9	$=\frac{9}{\left(47+9\right)}\times 100=\frac{900}{56}=16.07\approx 16$
2007-2008	56	$=\frac{56}{\left(56+13\right)}\times 100=\frac{5600}{69}=81.15\approx 81$	13	$=\frac{13}{\left(56+13\right)}\times 100=\frac{1300}{69}=18.84\approx 19$
2008-2009	60	$=\frac{60}{\left(60+16\right)}\times 100=\frac{6000}{76}=78.94\approx 79$	16	$=\frac{16}{\left(60+16\right)}\times 100=\frac{1600}{76}=21.05\approx 21$
2009-2010	63	$=\frac{63}{\left(63+18\right)}\times 100=\frac{6300}{81}=77.77\approx 78$	18	$=\frac{18}{\left(63+18\right)}\times 100=\frac{1800}{81}=22.22\approx 22$

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