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%
