CLAT 2020 Quantitative Techniques: Japanese Encephalitis

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

If the total number of males affected by Japanese Encephalitis in other states are 87 % more than the average number of males in Odisha, West Bengal, Chhattisgarh and Jharkhand, the total number of males affected in India is:

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 \(=\frac{15}{29} \times 29000=15000\)

The average number of males affected in these 4 states \(=\frac{(36000+30000+15000+15000)}{4}=24,000\)
The number of males affected in the rest of the states of India = 87% more than 24,000 = 24000 + 87% of 24000 = 44,880

The total number of males affected in India = 24000 + 44880 = 68,880.
