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

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 =

Directly we can take the male percentages to total.
i.e. U.P. Male = 3% of 15% 3276000.
Like this we can take M.P and GOA then we add.

How 3/5 comes at first step?
Ans:
Ratio of males and females in UP = 3 : 2
Number of Males = 3/(3+2) = 3/5 of 15% of N.

Ratio of males and females in UP = 3 : 2
