Since the average income rose from $12200 to$16300, the rise is $4100(16300 - 12200) This represents an increase of $$\frac{4100}{12200} * 100 = \frac{400000}{12000}$$ = approximately $$33\frac{1}{3}$$% (Option C) _________________ You've got what it takes, but it will take everything you've got e-GMAT Representative Joined: 04 Jan 2015 Posts: 1897 Re: In a certain city, the average income for a family of four rose from [#permalink] ### Show Tags 31 Jan 2018, 05:23 1 Bunuel wrote: In a certain city, the average income for a family of four rose from$12,200 in 1980 to $16,300 in 1986.
