The following data presents the cases of Japanese Encephalitis in five states of India.

What is the average number of males affected by Japanese encephalitis in all the five states?

Correct Answer: 20,600

To find the average number of males affected by Japanese encephalitis across all five states, we first calculate the total number of males affected in each state using the provided bar chart and ratio table.

Note: The bar graph shows the total number of persons affected (in thousands):
- Odisha: 57 thousand = 57,000
- West Bengal: 45 thousand = 45,000
- Chhattisgarh: 21 thousand = 21,000
- Jharkhand: 29 thousand = 29,000
- Andhra Pradesh: 13 thousand = 13,000

Next, we use the given ratio of Male : Female for each state to calculate the number of males affected:

1. Odisha:
Ratio of Male : Female = 12 : 7 (Total parts = 12 + 7 = 19)
$\text{Number of males}=\mathrm{57,000}\times \frac{12}{19}=\mathrm{3,000}\times 12=\mathrm{36,000}$

2. West Bengal:
Ratio of Male : Female = 6 : 3 (Total parts = 6 + 3 = 9)
$\text{Number of males}=\mathrm{45,000}\times \frac{6}{9}=\mathrm{5,000}\times 6=\mathrm{30,000}$

3. Chhattisgarh:
Ratio of Male : Female = 5 : 2 (Total parts = 5 + 2 = 7)
$\text{Number of males}=\mathrm{21,000}\times \frac{5}{7}=\mathrm{3,000}\times 5=\mathrm{15,000}$

4. Jharkhand:
Ratio of Male : Female = 15 : 14 (Total parts = 15 + 14 = 29)
$\text{Number of males}=\mathrm{29,000}\times \frac{15}{29}=\mathrm{1,000}\times 15=\mathrm{15,000}$

5. Andhra Pradesh:
Ratio of Male : Female = 7 : 6 (Total parts = 7 + 6 = 13)
$\text{Number of males}=\mathrm{13,000}\times \frac{7}{13}=\mathrm{1,000}\times 7=\mathrm{7,000}$

Now, calculate the total number of males affected across all 5 states:
$\text{Total males}=\mathrm{36,000}+\mathrm{30,000}+\mathrm{15,000}+\mathrm{15,000}+\mathrm{7,000}=\mathrm{1,03,000}$

Finally, find the average number of males affected:
$\text{Average number of males}=\frac{\mathrm{1,03,000}}{5}=\mathrm{20,600}$

Thus, the average number of males affected by Japanese encephalitis in all the five states is 20,600.
