Previous Year Questions 2020: Quantitative | Quantitative Techniques for CLAT

Number of females affected by Japanese encephalitis in West Bengal are what percentage (up to 1 decimal) more or less than that of females affected in Odisha?
(a) 28.6 % less
(b) 
29.7 % more 
(c) 26.8 % less
(d) 25.8 % more
Ans: (a)
Sol: Let us assume the number of males and females affected by Japanese encephalitis in West Bengal be 6x and 3x.
Also, let us assume the number of males and females affected bv Japanese encephalitis in Odisha be 12y and 7y.
According to the given data,
6x + 3x = 45000 
9x = 45000 
x = 5000 
Also, 12y + 7y = 57000 
19y = 57000 
y = 3000
So, number of females affected by Japanese encephalitis in West Bengal = 3x = 3 x 5000 = 15000
And, number of females affected by Japanese encephalitis in Odisha = 7y — 7 x 3000 = 21000 
So, percent change

What is the average number of males affected by Japanese encephalitis in all the five states?
(a) 9,000
(b) 13,500
(c) 18,400
(d) 20,600
Ans: 
(d)
Sol: Let us assume the number of males and females affected by Japanese encephalitis in Odisha be 12x and 7x.
According to the given data,
12x + 7x = 57000 
19x = 57000 
x = 3000
So, number of males affected by Japanese encephalitis in Odisha = 12x = 12 x 3000 = 36000
Also, let us assume the number of males and females affected by Japanese encephalitis in West Bengal be 6y and 3y.
According to the given data,
6y + 3y = 45000 
9y = 45000
Y = 5000
So, number of males affected by Japanese encephalitis in West Bengal = 6y = 6 x 5000  = 30000
Also, let us assume the number of males and females affected by Japanese encephalitis in Chhattisgarh be 5z and 2z.
According to the given data,
5z - 2z = 21000 
7z = 21000 
z = 3000
So, number of males affected by Japanese  encephalitis in Chhattisgarh = 5z = 5 x 3000 = 15000
Also, let us assume the number of males and females affected by Japanese encephalitis in Jharkhand be 15a and 14a.
According to the given data,
15a - 14a = 29000 
29a = 29000 
a = 1000
So, number of males affected by Japanese encephalitis in Jharkhand = 15a = 15 x 1 = 15000
Also, let us assume the number of males and females affected by Japanese encephalitis in Andhra Pradesh be 7b and 6b.
According to the given data,
7b - 6b = 13000 
13b = 13000 
b = 1000
So, number of males affected by Japanese encephalitis in Andhra Pradesh = 7b = 7 x 1 = 7000
Average number of males affected by Japanese encephalitis in all the five states
