    The average of graduate males and females \[=60%\] \[\therefore \]Male graduates\[=60%\] Let the total population be\[200\]. Then,    M         F                      Graduate             100       100                   (M+F)                                                 120                         M                     F % graduates       60%                  60%                         = 60                 = 60 Postgraduate      = 30% of 60      40% of 60                         = 18                 = 24 \[\therefore \]Total postgraduates (male + female) \[=18+24=42\] \[\therefore \]Required\[%=\frac{42}{200}\times 100=21%\]
