The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.

The percentage increase from 5 laps of race on the first day to 9 laps after several weeks is 80%
<h3>How to determine the percentage increase?</h3>
The distance ran are given as:
Initial = 5 laps
Final= 9 laps

Percentage = (Final - Initial)/Initial
So, we have:
Percentage = (9 - 5)/5
Evaluate
Percentage = 0.8
Express as percentage
Percentage = 80%
Hence, the percentage increase is 80%
