Both Betty and Wilma earn annual salaries of more than $50000. Is Wilma's annual salary greater than Betty's?

Notice that we are told that both Betty and Wilma earn annual salaries of more than $50,000.

(1) Betty's annual salary is closer to $50,000 than is Wilma's.

----$50,000---(Betty)----(Wilma)---- So, as you can see Wilma's annual salary is greater than Betty's. Sufficient.

(2) Betty's annual salary is closer to $35,000 than it is to Wilma's annual salary.

$35,000----$50,000---(Betty)----(Wilma)---- Again Wilma's annual salary is greater than Betty's. Sufficient.

Answer: D.

Hope it's clear.

Answer: D.

Hope it's clear.


I believe that OA is wrong.
It should be D.

Kindly check the OA and edit it.

Bunuel - Your explanation is spot on.

I am sorry, but the official answer does not make any sense for Statement 1. It is simply mathematically wrong.

Mathematically spoken the statement says: |Betty-50.000|<|Wilma-50.000| and not Betty-50.000 < Wilma-50.000
Let me make a numerical example. Betty earns 49.999 an Wilma earns 70.000. Obviously Betty's salary is closer than 50.000 though Wilma earns more. And the over way around: Let Betty earn 50.001 and Wilma 40.000, now still Betty's wage is closer to 50.000 though she now earns more than Wilma.

Stating that 1) is sufficient is simply wrong and I'm actually quite astonished people get away with such an answer so easily.

p.s.: The same argumentation holds for 2), so the correct answer must be C, as you can deduct from both statements that both wages must lie above 50.000; something you can't predict earlier.
