As the flights were in hundred , 11.9 = 11.9 x 100 = 1190
We have to calculate the average = 1190 / 5 = 238

The total number of flights cancelled in Punjab over the years, PA = 140 + 130 + 50 + 270 + 140 + 270 = 1000
The required percentage,
P = (320 / 1000) ×100 = 32%
Hence, 32% is the required answer.
