The difference between the maximum number of people involved and minimum number of people involved in various professions is:

Discuss
Solution:
Maximum people in any profession - Minimum people involved in any profession
Agriculture = 33.30%
Trade = Minimum = 6.70%
Difference = 33.30% - 6.70% = 26.60%
100% = 20000
1% = 200
26.6% = 200 × 26.6
           = 5320
