I get A. We have to find out if l >=2j , where l is lisas salary, and j is julie's salary.

from stat 1, l=j+20,000, in other words, is j+20,000 >=2j --> we get that 20,000 >=j. So, witht this known, no matter what number you pick for j, if you add 20,000 to it to get lisa's salary, you will see that its always at least twice as large.

from stat 2, you only know lisas salary and nothing about julies. insuff

I think it's C:
L>=J is not an assumption, it's a question though.
1: L= J+20 (nothing could be drawn from here)
2: L<40 (nothing too)

L=J+20 and L<40 so J<20
J<20 and L= J+20 so 2J<L

L=J+20 and L<40 so J<20
J<20 and L= J+20 so 2J<L

OA is C

Guys, 2J<40, L also <40, how do you know 2J<L?
I think the OA wrong!

Question: L >= 2J
(1). L = J + 20
J + 20 >= 2J
J > 20
But not sure about Lisa. Insufficient

(2) L < 40
From this statement alone we cannot identify what is J's salary. So insufficient

Combining (1) and (2)

L = J + 20; L < 40 and J > 20,
Comining this we can identify the solution; IMO C

Was Lisa's salary at least twice as much as Julie's annual salary?

Question: is $$L\geq{2J}$$?

(1) Lisa's annual salary was $20,000 more than Julies annual salary --> $$J=L-20$$ --> question becomes: is $$L\geq{2(L-20)}$$? --> is $$L\leq{40}$$? We don't know that. Not sufficient. Example: L=50 and J=30 --> answer NO; L=40 and J=20 --> answer YES. (2) Lisa's anual salary was less than$40,000 --> $$L<40$$, clearly insufficient as no info about J.

(1)+(2) From (1) question boiled down to: "is $$L\leq{40}$$" and (2) says that $$L<40$$, so the asnwer is YES. Sufficient.
