Year | Population to be covered (millions) | Water requirement (mid) | Actual or Projected Supplies (mid) |
1991 | 3.3 | 722 | 545 |
1994 | 4.35 | 913 | 680 |
2001 | 6.23 | 1105 | 1090 |
2011 | 8.19 | 1862 | 1906 |
2021 | 10.15 | 2224 | 1906 |
First we find the Growth rate per year of population from 2001 to 2011,
Growth rate per year of population from 2001 to 2011 = \(\frac{8.19 - 6.23}{6.23} \times 100\)
≈ 31.5%
To find the average growth we divide the growth rate with the number of years difference
= \(\frac{31.5}{10}\)
So, the average growth rate per year of population to be covered from 2001 to 2011 = 3.15%
The correct option is (A): 3.15\(\%\)
The Difference in per capita water requirements and the actual or projected supplies for year 1991 = 722 - 545 = 177
The Difference in per capita water requirements and the actual or projected supplies for year 1994 = 913 - 680 = 233
The Difference in per capita water requirements and the actual or projected supplies for year 2011 = 1862 - 1906 = -44
The Difference in per capita water requirements and the actual or projected supplies for year 2021 = 2224 - 1906 = 318
As we can see from the above, the maximum difference between water requirements and actual or projected supplies was in year 2021.
The correct option is (C): 2021
From the table we can see that, in year 2011 the actual or projected supplies exceeded/exceeds the water requirements
In that year = 1906 - 1862 = 44 mid water was more needed.
The correct option is (A): 2011
First we find out the per capita of actual or projected supplies per year given in the table
Per capita of water in actual or projected supplies for the year 1991 = \(\frac{545}{3.3}\) ≈ 165
Per capita of water in actual or projected supplies for the year 1994 = \(\frac{680}{4.35}\) ≈ 156
Per capita of water in actual or projected supplies for the year 2001 = \(\frac{1090}{6.23}\) ≈ 175
Per capita of water in actual or projected supplies for the year 2011 = \(\frac{1906}{8.19}\) ≈ 232.7
Per capita of water in actual or projected supplies for the year 2021 = \(\frac{1906}{10.15}\) ≈ 188
So, the maximum per capita of actual or projected supplies as \(\frac{litres}{day}\) was in year 2011 around 232.7
The correct option is (C): 232.7
First we will find out the Difference in per capita water requirements and the actual or projected supplies for year for each year given in the table.
The Difference in per capita water requirements and the actual or projected supplies for year 1991 = 722 - 545 = 177
The Difference in per capita water requirements and the actual or projected supplies for year 1994 = 913 - 680 = 233
The Difference in per capita water requirements and the actual or projected supplies for year 2011 = 1862 - 1906 = -44
The Difference in per capita water requirements and the actual or projected supplies for year 2021 = 2224 - 1906 = 318
So, from the above we can clearly see that, the least difference in per capita water requirements and the actual or projected supplies was in year 2011.
The correct option is (B): 2011
Per capita of water in actual or projected supplies in the year for the year 1991 = \(\frac{545}{3.3}\) ≈ 165
Per capita of water in actual or projected supplies in the year for the year 1994 = \(\frac{680}{4.35}\) ≈ 156
Per capita of water in actual or projected supplies in the year for the year 2001 = \(\frac{1090}{6.23}\) ≈ 175
Per capita of water in actual or projected supplies in the year for the year 2021 = \(\frac{1906}{10.15}\) ≈ 188
We can see that, the lowest per capita of water in actual or projected supplies was in year 1994.
The correct option is (C): 1994
