A grocer is storing soap boxes in cartons that measure 25 inches by 42 inches by 60 inches. If the measurement of each soap box is 7 inches by 12 inches by 5 inches, then what is the maximum number of soap boxes that can be placed in each carton?	Choose the most appropriate option
A) 210	B) 150	C) 280	D) 300	E) 420

Solution: however the process of dividing the volume of box by the volume of a soap seems flawed but it does work in this case due to the numbers   Dimensions of the box =25*42*60   Dimensions of the soap = 5*12*7   placing the 7 inch side along 42 inch side we get 6 soaps in a line and in a similar way 5 along 25 and 6 along 60   we get = 5x6x5 = 150   so the question is why this particular arrangement, in order to maximize number of soaps we need to minimize the space wasted and this is the only config where we dont waste any space so we can expect the maximum number   the answer is (150)
Answer: B
The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and inversely proportional to the concentration of chemical T present. If the concentration of chemical T is increased by 100 percent, which of the following is closest to the percent change in the concentration of chemical A required to keep the reaction rate unchanged?  Choose the correct choice from the following choices
A) 100% decrease	B) 50% decrease	C) 40% decrease	D) 40% increase	E) 50% increase

Solution: Let A and T be the concentratrations of the individual chemicals.   Rate of chemical reaction = A^2/T   Since new T is increased by 100%   Rate = A^2/(2T)   For the rate to be constant, new value of A should be square root(2)   So new value of A = 1.414A   That means A is increased by 41.4%   Nearest solution is 40% increase

How many of the following numbers are divisible by 132?
264, 396, 462, 792, 968, 2178, 5184, 6336,528,1320 Select the correct option:	A) 4	B) 5	C) 6	D) 7	E) 8

Solution: Explanation:   A number is divisible by 132, if it is divisible by each one of 11, 3 and 4.   Clearly, 968 is not divisible by 3. None of 462 and 2178 is divisible by 4.   Also, 5184 is not divisible by 11.   Each one of remaining 6 is divisible by each one of 11, 3 and 4 and therefore, by 132.   Answer: 6

Joe’s average (arithmetic mean) test score across 4 equally weighted tests was 90. He was allowed to drop his lowest score. After doing so, his average test score improved to 95. What is the lowest test score that was dropped?  Choose the correct choice from the following answers:	A) 20	B) 25	C) 55	D) 75	E) 80

Solution: The arithmetic mean of 4 equally weighted tests was 90. So what we can assume is that we have 4 test scores, each 90.   He dropped his lowest score and the avg went to 95. This means that the lowest score was not 90 and other three scores had given the lowest score 5 each to make it up to 90 too. When the lowest score was removed, the other 3 scores got their 5 back. So the lowest score was  3 *5= 
 3 *5 = 15
15 less than 90.   So the lowest score= 90 - 15= 
90 - 15 = 75

In the county of Veenapaniville, there are a total of 50 high schools, of three kinds: 25 public schools, 16 parochial schools, and 9 private independent schools. These 50 schools are divided between three districts: A, B, and C. District A has 18 high schools total. District B has 17 high schools total, and only two of those are private independent schools. If District C has an equal number of each of the three kinds of schools, how many private independent schools are there in District A? Choose the most appropriate option: A) 2 B) 3 C) 4 D) 5 E) 6

Solution: “In the county of Veenapaniville, there are a total of 50 high schools, of three kinds: 25 public schools, 16 parochial schools, and 9 private independent schools.”   “District A has 18 high schools total.”   “District B has 17 high schools total, and only two of those are private independent schools.”   “District C has an equal number of each of the three kinds of schools.” Hmm. That’s not a simple number. Let’s put that on hold for a moment. So far, from the matrix it looks like we could figure out the missing number in the “totals” row. That number must be 15, because 18 + 17 + 15= 
18 + 17 + 15 = 50
50.   Now, go back to that last fact: “District C has an equal number of each of the three kinds of schools.” Now that makes sense. District C has 15 schools, so it must have 5 of each kind:   The question is asking: “how many private independent schools are there in District A?” Well, now that’s just a matter of adding across the “private independent” row. We know 2 + 2 + 5= 
2 + 2 + 5 = 9
9, so the missing number must be 2.   There’s still a good deal of information we can’t figure out from the information given in the question, but we are able to answer the specific question asked here. There are 2 private independent schools in District 2, so the answer= (2).

The radius of a cylindrical water tank is reduced by 50%. However, the speed by which water is filled into the tank is also decreased by 50%. How much more or less time B will it take to fill the tank now?
Select the correct option:  A) 50% less time  B) 50% more time  C) 75% less time  D) 75% more time  E) 100% more time

Solution: (VC)Volume of the cylinderical vessal is directly proportional to R^2.   So if radius is 50% less volume will be 1/4th of the original volume.(VC/4)   Now if with velocity V tank can be filled in T1 time of volume VC   So now Velocity is 50% less i..e V/2   So time taken to fill the capacity VC/4 by V/2 velocity is T2.   VT1 = VC   V/2*T2 = VC/4   So T1/T2 = 1/2   So Tank will be filled in less time. that is B=50 % less.50% less time

Solution: Speed of train relative to man = 63 - 3= 
63 - 3 = 60
60 km/hr.= 60 * 5/18 = 50/3 m/sec.   Time taken to pass the man = 500 * 3/50= 
500 * 3/50 = 30
30 sec.   Answer:30 sec
Answer: B
In a stack of cards, 11 cards are blue and the rest are red. If 2 cards are to be chosen at random from the stack without replacement, the probability that the cards chosen will both be blue is 5/6 . What is the number of cards in the stack?	Choices:
A) 10
B) 11
C) 12
D) 15
E) 18

Solution: This question can be solved by TESTing THE ANSWERS.   Answer C: 12 total cards   With 12 total cards, and 11 blue cards, the probability of pulling two blue cards is...   (11/12)(10/11) = 110/132 ~= 5/6   This is an exact MATCH for what we were told, so this MUST be the answer.   Final Answer:   12

Answer: C
If the sum of five consecutive positive integers is A, then the sum of the next three consecutive integers in terms of A is:  Choices.
A) 3A/5
B) 3A/5 +12
C) A
D) 5A/3
E) 5A/3 +12

Solution: In Case of Consecutive Integers or Integers in Arithmetic Progression Mean = Median   I.e. Median = A/5 = Mean = Third Integer   First Integer = A/5 - 2   Second Integer = A/5 - 1   Third Integer = A/5   Fourth Integer = A/5 + 2   Fifth Integer = A/5 + 2   i.e.   Sixth Integer = A/5 + 3   Seventh Integer = A/5 + 4   Eighth Integer = A/5 + 5   Now Mean of next 3 Integers = Median = A/5 + 4   i.e. Sum of Next 3 integers = (A/5 + 4)*3 = 3A/5 +12   Answer: option 3A/5 +12

What is the smallest no. that should be added to 45454 to make it exactly divisible by 9?	Choose the most appropriate option:
A) 1
B) 3
C) 5
D) 6
E) 9

Solution: If a number is divisible by 9, the sum of its digits must be a multiple of 9.   Here, 4+5+4+5+4=22, the next multiple of 9 is 27.   5 must be added to 45454 to make it divisible by 9   5
