Answer : Option C

Explanation :

Number of males in U.P = [ $\frac { 3 } { 5 }$ of (15% of N )] = $\frac { 3 } { 5 }$ X $\frac { 15 } { 100 }$ x N =  9 x $\frac { N } { 100 }$

where N = 3276000.

Number of males in M.P =[ $\frac { 3 } {4}$ of (20% of N ) = $\frac { 3 } {4}$ x $\frac { 20 } { 100 }$ x N = 15 x $\frac { N } { 100 }$

Number of males in Goa = [ $\frac { 3 } {8}$ of  (12 % of N ) = $\frac { 3 } {8}$ x $\frac { 12 } { 100 }$ x N = 4.5 x $\frac { N } { 100 }$

Total number of males in these three states

= (9 + 15 + 4.5) x$\frac { N } { 100 }$

                                                                             = [ 28.5  x  $\frac { N } { 100 }$ ] 

 Required Percentage = [ $\frac { (28.5 * N/100) } { N }$ x 100 ] % = 28.5%
