**MathMate**, Friday, February 4, 2011 at 6:39amLet the score be S.

The current total score is

73*23.

The required total score is

74*24

The required score of the last paper is therefore

74*24-73*23

=?

**Raymond**, Sunday, June 12, 2011 at 2:51pm97 However my solution of the problem went a different way than

MathMate. The 24th student would have a base score of 73 and add 24 to it (to raise the average score of all students by 1) would give 97 as the answer.
