    Step-by-step explanation:

    Given;

    The average marks of 40 students in an examination =34

    It was found that one student had been wrongly entered as 62 instead of 26.

    The marks of students in an examination=40*34=1360

    62-26=36

    1360-36=1324

    After correction of marks the mean =1324/40

    =33.1

    After correction of marks the mean is 33.1
