    Answer : Option C

    Explanation :

    Required average = \( [\frac { 50.25 *16+45.15*8 } { 16+8 }]\)

                       

                                  = \([\frac { 804+36.120 } { 24 } ]\)

                       

                                  =   \( \frac { 1165.20 } { 2 4} \)

                                 

                                  =  48.55
