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.

Problem Solving :

( Most of the questions have been re-framed and the values have been substituted with simple ones, but the type of the questions have been preserved )

2. A cab-for-hire company costs $1.75 for the first quarter mile and fifteen cents for each additional quarter mile. What is the maximum distance you can travel with $4.90?

4. A salesman's income was divided between commission and regular salary. His salary, therefore, varied from week to week. His weekly salaries over a 5-week period were: $406.20, $413.50, $420.00, $425.00 and $395.30. What was his average weekly salary over the 5 week period?
Ans: $412.00

5. A train travels 15 miles per ton of coal when it carries no cargo. When the train is filled with cargo, it travels 80% as far on a ton of coal as it does when it has no cargo. If the train is filled with cargo, how many tons of coal will the train use to travel 160 miles?

9. Sam earns $12 per hour and Peter earns $10 per hour. Approximately how much less, as a percentage, does Peter earn than Sam per hour?
Ans: 17 %

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.

11. In 2007, Ramond had a collection of 48 stamps. Since then he has given away 13 stamps, purchased 17 new stamps and traded 6 of his stamps to Peter for 8 of Peter's stamps. Since 2007, what has been the net percent increase in Ramond's collection?
