GRE UPDATE - OCTOBER 2007 QUANTS

Hi guys and girls,

I was able to collect a total of only 18 questions for GRE OCTOBER QUANTS 2007 as of now. That too only problem solving type. I did receive quite a few comaprison questions, but I was not able to verify them due to incomplete information about the two columns without which I cannot guarantee reliable answers. I am sill analysing them. It will probably take me two to three days to consolidate, verify and then post them. If you have doubts about how to solve any of the following questions, you may request for explanation, I will be glad to send you adequate elucidation on those particular questions. More quants questions for GRE OCTOBER 2007 will follow.

10. The original price of a furniture was $50.00. Because the manager of the furniture store thought he could get more money for the furniture, he increased the price of the furniture to 108% of its original price. After a week, the furniture had not sold, so the manager then discounted the price by 10%, and the furniture was finally sold. At what price was the furniture sold? (Values have been changed and sentences re-framed )
Ans: $48.60

**Short method to solve : Since 108% of $50 = (1.08)(50) = $54, the furniture was offered for sale at $54.00. It was sold for 90% of $54 since there was a 10% discount. Therefore, the furniture was sold for (.9)($54) or $48.60. Several questions appear of this type.
