Answer 2

hey buddy i hope your question has a little mistake i.e4065 must be 40,65

arithmetic mean of marks obtained by 9 students--->

then,

n(total number of students)

sum of all marks of all students=52+57+40+70+43+40+65+35+48=450

then arithmetic mean=

           sum of all students/n

         =>450/9

         =>50
