#86# is his final grade.
He lost #24# points and gained #10# points.

There are #25# questions total. Assuming that answering all #25# questions correctly earns you a #100#, let's calculate Ned's score.

First, Ned loses #4# points each for #6# questions he answered incorrectly. So:

#4 * 6 = 24#
#100 - 24 = 76#

His current grade is a #76#. However, he answered a bonus question and earned #10# points. So:

#76 + 10 = 86#

#86# is his final grade.

He lost #24# points and gained #10# points.
