mean=46+64+87+41+58+77+35+90+55+35+92

          _____________________________________

                                 11

       =                       680

        ________________________________

                                 11

       =61.81

mean of this 11 nos.=61.81

therefore,total of 11 nos.=11*61.81

                                    =679.91

new total=679.91-(90-19)

             =679.91-71

              =608.91

new mean=         608.91

                ________________

                           11

               =55.3554545455
