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 :
To solve this problem, we need to determine the total population of males in India based on the given information about the population distribution in the west zone. Let's break it down step-by-step:
- We are given that 50% of the total population of the west zone are males. This is also equal to 10% of the total population of males in India.
- Let the total population of males in India be \(M\).
- According to the problem statement, 50% of the population of the west zone is equal to 10% of \(M\). Therefore, we can express this relationship mathematically as: \(\frac{50}{100} \times P_w = \frac{10}{100} \times M\) where \(P_w\) is the total population of the west zone.
- We also know that the total population of females in the west zone is 50 million. Given that males constitute 50% of the west zone population, the population of males is also 50 million. Thus, 100% of the west zone population is 100 million (since 50 million males + 50 million females = 100 million).
- Substituting this into our equation: \(50 = \frac{10}{100} \times M\)
- To find \(M\), solve for \(M\): \(M = 50 \times \frac{100}{10} = 500\) million.
Therefore, the total population of males in India is 500 million.
This calculation aligns with the information given in the question, and confirms that the correct answer is indeed:
- 500 million
In the attached pie chart, the distribution of zones helps contextualize the problem, but the calculations we performed do not directly depend on specific percentage values from the chart.
