[#permalink] 21 Apr 2011, 20:42 Hey when I doing Kaplan test I just marked C bcos I was short of time 7.9ab7 My thoughts- From 1) we have a can be 3 or 4 If a is 3 then b>=5 if a is 4 then b<=4 From 2) we have a is atleast 4. No information about b 1) + 2) a is 4 and b<=4. But then b must be highest since The dollar value when rounded to nearest tenth of a cent is 9.500. So I got the value as 9.9447 It doesn't work either ! You can see the discrepancy. I am thinking if I missed a puzzle piece.
