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%.

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?

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.
We know that 3276000 value remains same for all states.

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%.

Does any one have a simpler solution to this problem? I don't understand the working out.
