CLAT 2020 Quantitative Techniques: Japanese Encephalitis

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?

Let's calculate the number of males affected by encephalitis in each state...

Number of males affected in a state $=\frac{\text { ratio of males }}{\text { total ratio }} \times \text { Total number of people effected by encephalitis in a particular state }$
Number of males affected in Odisha $=\frac{12}{19} \times 57000=36000$
Number of males affected in West Bengal $=\frac{6}{9} \times 45000=30000$
Number of males affected in Chattisgarh $=\frac{5}{7} \times 21000=15000$
Number of males affected in Jharkhand $=\frac{15}{29} \times 29000=15000$
Number of males affected in Andhra Pradesh $=\frac{7}{13} \times 13000=7000$

The average number of males affected in the 5 states $=\frac{(36000+30000+15000+15000+7000)}{5}=20,600$
