I got it.. The answer should be 2.8/8 which makes it 35%...Oh lord..cant believe I fell for the trap.
That's great that you made that mistake here, rather than on the test. When I first started studying for the GMAT I had a problem that was osmething like "If a company of 3000 employees was 1/3 women, and 300 women quit, what is the new percentage of women". Well, I figured out everything right, but what i went to do the final percentage, I did not take away the women that quit form the total employees. You made a similar error. So now, you will always remember this problem and not make the mistake again. Therefore, you are successful.
