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

What is the percentage (up to 1 decimal) of females affected by ‗Japanese encephalitis‘ of the total affected population across five states?

The correct option is 37.6.

From the given bar chart and ratio table in the image:

1. Data for total affected population (in thousands):
• Odisha: 57
• West Bengal: 45
• Chhattisgarh: 21
• Jharkhand: 29
• Andhra Pradesh: 13

Total affected population across all five states:
$\text{Total Population}=57+45+21+29+13=165\text{thousand}$

2. Calculation of affected females in each state:

• Odisha:
Ratio of Male : Female = 12 : 7
Total parts = 12 + 7 = 19
$\text{Females}=57\times \frac{7}{19}=3\times 7=21\text{thousand}$

• West Bengal:
Ratio of Male : Female = 6 : 3
Total parts = 6 + 3 = 9
$\text{Females}=45\times \frac{3}{9}=5\times 3=15\text{thousand}$

• Chhattisgarh:
Ratio of Male : Female = 5 : 2
Total parts = 5 + 2 = 7
$\text{Females}=21\times \frac{2}{7}=3\times 2=6\text{thousand}$

• Jharkhand:
Ratio of Male : Female = 15 : 14
Total parts = 15 + 14 = 29
$\text{Females}=29\times \frac{14}{29}=14\text{thousand}$

• Andhra Pradesh:
Ratio of Male : Female = 7 : 6
Total parts = 7 + 6 = 13
$\text{Females}=13\times \frac{6}{13}=6\text{thousand}$

3. Total number of females affected across all five states:
$\text{Total Females}=21+15+6+14+6=62\text{thousand}$

4. Percentage of females affected out of total population:
$\text{Percentage}=\left(\frac{62}{165}\right)\times 100$

$\text{Percentage}=\frac{6200}{165}\approx 37.575\%$

Rounding up to 1 decimal place gives 37.6%.
