To calculate the relative product performance index, we need to calculate the geometric mean of the four aspects of product performance (speed, resolution, memory, and price). 
For PrintWorth Inc, the geometric mean is the fourth root of (5x5x5x1) which is 4.22. 
For its competitors:
Competitor A: fourth root of (3x5x5x2) = 4.49
Competitor B: fourth root of (5x2x2x6) = 3.16
Competitor C: fourth root of (1x1x1x8) = 1
Therefore, the relative product performance index for PrintWorth Inc. is (4.22/3.23) x 100 = 130.
