Q1:

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?

A 25%

B 27.5%

C 28.5%

D 31.5%

ANS:C - 28.5%

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
Therefore Total number of males in these three states
= (9 + 15 + 4.5) x N
100
= ( 28.5 x N ) .
100
Therefore Required Percentage = [
( 28.5 x N )
100
x 100 ] % = 28.5%.
