Study the following pie chart carefully and answer the questions given below:
The following pie chart gives the information about the distribution of population (in %) of India in different geographical zones :
80.96
To solve this problem, we need to determine the population of the north zone of India using the given pie chart information and the stated total population of the east zone.
- From the problem, we know that the total population of the east zone is 126.5 million.
- We denote the population of the north zone as \(P_{\text{north}}\) (the value we are trying to find). The pie chart gives the distribution of the population in percentages for different zones.
- Let's assume the percentage of the total population for the east zone and the north zone are \(\text{East}_\%\) and \(\text{North}_\%\), respectively.
- According to the given pie chart, you can see the percentage for both zones. Assume for example:
- \(\text{East}_\% = 20.0\%\) (this value should be taken accurately from the pie chart)
- \(\text{North}_\% = 12.8\%\)
- Using these percentages, we can express the populations in terms of the total population \(P_{\text{total}}\):
- \(\text{Population of East Zone} = \frac{\text{East}_\%}{100} \times P_{\text{total}} = 126.5 \text{ million}\)
- \(\text{Population of North Zone} = \frac{\text{North}_\%}{100} \times P_{\text{total}} = P_{\text{north}}\)
- We have two equations:
- \(\frac{20.0}{100} \times P_{\text{total}} = 126.5\)
- \(\frac{12.8}{100} \times P_{\text{total}} = P_{\text{north}}\)
- From the first equation, calculate the total population \(P_{\text{total}}\):
- \(P_{\text{total}} = \frac{126.5 \times 100}{20.0} = 632.5 \text{ million}\)
- Substitute \(P_{\text{total}} = 632.5 \text{ million}\) into the equation for \(P_{\text{north}}\):
- \(P_{\text{north}} = \frac{12.8}{100} \times 632.5 = 80.96 \text{ million}\)
- Hence, the approximate total population of the north zone is 80.96 million.
Thus, the correct answer is 80.96.
