Old system, base 30, correct 4, incorrect -1, blank 0, total 30 questions. New system, base 0, correct 5, incorrect 0, blank 2, total 30 questions. translate the old system into the new system: base 0, correct 5, incorrect 0, blank 1. Therefore the difference in score is the difference on the number of blanks. No need for any systems of equations. |
