in some months last year, natalie, a sales representative at SmithKline & Beecham, went over $60000 in sales. in how many months last year did she do so?

1. last year, the number of months in which natalie went over $60000 was 8 months more than the number of months in which she did not.

2. last year, the number of months in which natalie went below $60000 was 1/5 the number of months in which she did not.

2. last year, the number of months in which natalie went below $60000 was 1/5 the number of months in which she did not.

The possibilities are:

Sales above (over) $60000 = a Sales equal to $60000 = e Sales below to $60000 = b

1: a - b -e = 8

if a = 9, b = 1 and e = 2 if a = 10, b = 2 and e = 0

so nsf..

2: b = 1/5 (a+e) 5b = (a+e) so "b" has to be 2 and (a+e) = 10 but do not know what "a" and "e" are. nsf.

1&2: since "a" cannot be 9 cuz if so "e" has to be 2 and (a+e) becomes 11 which is wrong (from st... 2). so a has to be 10 and e equal to 0 to have a+e = 10.

no wonder I didn't do well on the GMAT Quant. I didn't know GMAT was this tricky. I didn't consider the equal to $60,000 part. A makes sense in that regards.
