The ratio of flour to water to sugar in a recipe is 10:6:3. The ratio in a new recipe calls for a doubling of the ratio of flour to water from the original recipe and a halving of the ratio of flour to sugar. If the new recipe calls for 2 cups of water, how much sugar is required?
Answers
A) 3 B) 4 C) 5 D) 6 E) 7

Solution: The ratio of flour to water is 10:3.   The ratio of flour to sugar is 5:3=10:6.   The new ratio of flour to water to sugar is 10:3:6   If we need 2 cups of water, then we need 4 cups of sugar.   The answer is 4.

Answer: D
AV + CD = AAA, where AV and CD are two-digit numbers and AAA is a three digit number; A, V, C, and D are distinct positive integers. In the addition problem above, what is the value of C? Pick one.
A) 1  B) 3  C) 7  D) 9  E) Cannot be determined

Solution: Since AV and CD are two-digit integers, their sum can give us only one three digit integer of a kind of AAA: 111.   So, A=1 and we have 1V+CD=111   Now, C can not be less than 9, because no two-digit integer with first digit 1 (1V<20) can be added to two-digit integer less than 90, so that to have the sum 111 (if CD<90, so if C<9, CD+1V<111).   Hence C=9.   Answer: 9.

A vendor sells 50 percent of the apples he had and throws away 20 percent of the remainder. The next day, the vendor sells 50 percent of the remaining apples and throws away the rest. In total, what percent of his apples does the vendor throw away?
Options
A) 30  B) 35  C) 40  D) 45  E) 50

Solution: Let x be the original number of apples.   On day one, the vendor throws away (0.2)(0.5)x=0.1x.   The remaining apples are (0.8)(0.5)x = 0.4x.   On day two, the vendor throws away (0.5)(0.4)x=0.2x.   The vendor throws away a total of 0.1x + 0.2x = 0.3x.   The vendor throws away 30 percent of the apples.   The answer is 30. 0.1  + 0.2= 
 0.1  + 0.2 = 0.3
0.3x.   The vendor throws away 30 percent of the apples.   The answer is 30.

E) 3 and 6

Solution: Work = (A)(B)/(A+B) where A and B are the individual times of each entity.   Here, we're told that (working together) the two teams would complete a job in 6 days. This means that (individually) each team would take MORE than 6 days to do the job.

A) 72%
B) 42%
C) 56%
D) 12%
E) 22%

For which of the following functions f is f(z) = f(1-z) for all z?	Choose the correct option
A) f (x) = 1 - x  B) f (z) = 1 - z^2  C) f (z) = z^2 - (1 - z)^2  D) f (z) = z^2*(1 - z)^2  E) f (x) = x/(1 - x)

Solution: I remember seeing this problem in a GMATprep test. I think choice D should be F(z)=(z^2) (1-z)^2. If that is true then substituting (1-z) for will give us the same function back and the answer choice is f (z) = z^2*(1 - z)^2, where the function is multiplicative

Sam is training for the marathon. He drove 12 miles from his home to the Grey Hills Park and then ran 6 miles to Red Rock, retraced his path back for 2 miles, and then ran 5 miles to Rock Creek. If he is then n miles from home, what is the range of possible values for n? Choose the correct choice from the following choices:
A) 1 ≤ n ≤23
B) 3 ≤ n ≤21
C) 5 ≤ n ≤19
D) 6 ≤ n ≤18
E) 9 ≤ n ≤15

Solution: ANSWER: C To find the maximum and minimum range for his distance from home, assume that he traveled either directly toward his home or directly away from his home. The range then is between 12+6-2+5= 
12+6-2+5 = 21
21 for the maximum, and   12-6+2-5= 
  12-6+2-5 = 3
3 for the minimum, so 3 ≤ n ≤21 is the answer
