32) C

We can use approximate values for the earnings. 

Top 20% earn = $162,000 + $51,000 = $213,000

Bottom 20% earn = $16,000 + $17,000 = $33,000

Ratio = 213000 : 33,000 = 6.5 : 1
Since we rounded down the bottom 20% and rounded up the top 20%, we need to decrease the overall ratio. So, C (6 : 1) is the answer.
