Explanations
1. The total length of roads in the year 1990 = 30,00,000 kms.
Urban roads are 7% of total roads. The length of urban roads = 7 X 30,00,000/100 = 2,10,000.
2. The maximum increases are 2 00,000 kms in both 1996-97 and 1997-98.
Percentage increase in 1996-97 = 2,00,000/25,00,000 * 100 = 8%.
Percentage increase in 1997-98 = 2,00,000/27,00,000 * 100 = 7.4%.
In other years, the increase is only 1,00,000 kms. So they obviously won’t be anywhere near to the above two years. Overall, the highest percentage increase is for 1996-97.
3. The length of highways in the year 1996 = 75% of 2500 = 75 X 2500/100 = 1875 thousand kms.
The length of highways in 1999 = 86% of 3000 = 86 X 3000/100 = 2580 thousand kms.
The increase in length of highways = 7,05 thousand kms.
4. The percentage share of highways in 2000 = 86 + 4 = 90%.
The increase in total length = 5% = 5 X 3000 / 100 = 150 thousand kms. The total length in the year 2000 = 3150 thousand kms.
The length of highways = 90 X 3150 / 100 = 2835 thousand kms
5. Length of project roads in 1995 = 0 km.
Length of project roads in 1999 = 7% of 3000 thousand km = 210 thousand kms.
Increase over these four years is therefore = 210,000 kms.
So, increase per year = 210,000/4 = 52,500 km.
