Question

In the table given below, the information is given about roads. Using this draw sub-divided and percentage bar-diagram (Approximate the percentages to the nearest integer)

Year	Permanent Roads ( Lakh km.)	Temporary Roads ( Lakh km.)
2000-2001 2001-2002 2003-2004 2007-2008	14 15 17 20	10 11 13 19

Answer 1

In the table given below, the information is given about roads.

Year	Permanent Roads ( Lakh km.)	Percentage of permanent roads	Temporary Roads ( Lakh km.)	Percentage of temporary roads
2000-2001	14	$=\frac{14}{\left(14+10\right)}\times 100=\frac{1400}{24}=58.33\approx 58$	10	$=\frac{10}{\left(14+10\right)}\times 100=\frac{1000}{24}=41.66\approx 42$
2001-2002	15	$=\frac{15}{\left(15+11\right)}\times 100=\frac{1500}{26}=57.69\approx 58$	11	$=\frac{11}{\left(15+11\right)}\times 100=\frac{1100}{26}=42.30\approx 42$
2003-2004	17	$=\frac{17}{\left(17+13\right)}\times 100=\frac{1700}{30}=56.66\approx 57$	13	$=\frac{13}{\left(17+13\right)}\times 100=\frac{1300}{30}=43.33\approx 43$
2007-2008	20	$=\frac{20}{\left(20+19\right)}\times 100=\frac{2000}{39}=51.28\approx 51$	19	$=\frac{19}{\left(20+19\right)}\times 100=\frac{1900}{39}=48.71\approx 49$

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