Study the following graph and the table and answer the questions given below.
Data of different states regarding population of states in the year 1998
Total population of the given States = 3276000.
States  Sex and Literacy wise Population Ratio  
Sex  Literacy  
M  F  Literate  Illiterate  
A.P  5  3  2  7 
M.P  3  1  1  4 
Delhi  2  3  2  1 
Goa  3  5  3  2 
Bihar  3  4  4  1 
U.P.  3  2  7  2 
T.N.  3  4  9  4 
1.
What will be the percentage of total number of males in U.P., M.P. and Goa together to the total population of all the given states?
Answer: Option
Explanation:
Number of males in U.P =  3  of (15% of N)  =  3  x  15  x N = 9 x  N  .  
5  5  100  100 
where N = 3276000.
Number of males in M.P =  3  of (20% of N)  =  3  x  20  x N = 15 x  N  .  
4  4  100  100 
Number of males in Goa =  3  of (12% of N)  =  3  x  12  x N = 4.5 x  N  .  
8  8  100  100 
Total number of males in these three states 



Required Percentage = 

x 100  % = 28.5%.  
N

First, find a total number of males.
UP = 3/5 * (15% of 3276000) = 294840
MP = 3/4 * (20% of 3276000) = 491400
GOA = 3/8 * (12% of 3276000) = 147420
Now % = total no. Of males(UP + MP + GOA) divide by 3276000* 100.
= 28.5%.
UP = 3/5 * (15% of 3276000) = 294840
MP = 3/4 * (20% of 3276000) = 491400
GOA = 3/8 * (12% of 3276000) = 147420
Now % = total no. Of males(UP + MP + GOA) divide by 3276000* 100.
= 28.5%.

Why we have to add 3+2 in the first step?

Here They have taken the whole ratio of the population of M +F.

In the question they didn't mention that the men and female are in the ratio.

U.P (Male, Female ratio) = 3 : 2 = 3/(3 + 2) = 3/5.
M.P = 3:1 = 3/4.
Goa = 3:5 = 3/8.
We know that 3276000 value remains same for all states.
So, take only the percentages and assume 3276000 as 'N'.
U.P = Population percentage = 15%.
M.P = 20%.
Goa = 12%.
No of men in U.P = 3/5 (15/100) N = (9/100) N.
M.P = 3/4 (20/100) N = (15/100) N.
Goa = 3/8 (12/100) N = (4.5/100) N.
Adding these three, we get (28.5/100) N.
Required % = {(28.5/100)N/N } * 100 = 28.5%.
M.P = 3:1 = 3/4.
Goa = 3:5 = 3/8.

M.P = 3/4 (20/100) N = (15/100) N.
Goa = 3/8 (12/100) N = (4.5/100) N.
Adding these three, we get (28.5/100) N.
Required % = {(28.5/100)N/N } * 100 = 28.5%.
