QUESTION #15:
How many words (with or without meaning) can be formed using all the letters of the word “SELFIE” so that the two E’s are not together?  Select the correct option:
A) 660	B) 600	C) 500	D) 300	E) 240

Solution: The question is asking the total number of arrangements possible with the letters of the word “SELFIE” where two E’s are not together.   Arrangements when two E’s are not together = Total arrangements - Arrangements when two E’s are together   In total there are 6 letters but two are identical. so we can arrange in 6! ways. but we divide for those objects that are identical. so divide by 2!. Hence,   Total arrangements = 6!/2!   Now two E's are coupled together. Consider this couple (EE) as one letter. apart from this there are 4 more letters. so we can arrange these 5 different objects in 5! ways.   Two E's can arrange themselves in 2! ways, but we divide for those objects that are identical. so divide by 2!. so arrangement for E's would be 2!/2!.   Hence, Arrangements when two E’s are together = 5! * (2!/2!)   Arrangements when two E’s are not together = 6!/2! - 5! = 5! * ( 6/2 -1 ) = 120 * 2= 
120 * 2 = 240

Solution A is 20% salt and Solution B is 70% salt. If you have 30 ounces of solution A and 60 ounces of solution B, in what ratio could you mix Solution A with Solution B to produce 50 ounces of a 50% salt solution?	Choose the correct choice from the following answers.
A) 6:4
B) 6:14
C) 2:3
D) 4:6
E) 3:7

Solution: Forget the volumes for the time being.   You have to mix 20% and 80% solutions to get 50%. This is very straight forward since 50 is int he middle of 20 and 80 so we need both solutions in equal quantities. If this doesn't strike, use   w1/w2 = (A2 - Aavg)/(Aavg - A1)   w1/w2 = (70 - 50)/(50 - 20) = 2/3   So the volume of the two solutions will be equal. Answer has to be 2:3   2:3

In a certain animal shelter, the ratio of the number of dogs to the number of cats is 15 to 7. If 16 additional cats were to be taken in by the shelter, the ratio of the number of dogs to the number of cats would be 15 to 11. How many dogs are in the shelter?	Choose the most appropriate option.
A) 15
B) 25
C) 30
D) 45
E) 60

Solution: This ratio question can be solved in a couple of different ways. Here's an Algebraic approach...   We're told that the ratio of the number of dogs to the number of cats is 15:7. We're then told that 16 more cats are added to this group and the ratio becomes 15:11. We're asked for the number of dogs.   Algebraically, since the number of dogs is a multiple of 15 and the number of cats is a multiple of 7, we can write this initial relationship as...   15X/7X   When we add the 12 cats and factor in the 'ending ratio', we have an equation....   15X/(7X+16) = 15/11   Here we have 1 variable and 1 equation, so we can solve for X....   (15X)(11) = (7X+16)(15)   (X)(11) = (7X+16)(1)   11X = 7X + 16   4X = 16   X = 4   With this X, we can figure out the initial number of dogs and cats...   Initial dogs = 15X = 15(4) = 60   Final Answer:60

Solution: Let the speed of each train be x m/sec.   Then, relative speed of the two trains = 2x m/sec.   So, 2x =	(120 + 120)/12   => 2x = 20   => x = 10.   Therefore Speed of each train = 10 m/sec =(10 x	(18/5))	km/hr = 36 km/hr.   Answer :36
Answer: C
The cost to rent a small bus for a trip is x dollars, which is to be shared equally among the people taking the trip. If 10 people take the trip rather than 20, how many more dollars, in terms of x, will it cost per person? Choose the most appropriate option.
A) x/6 B) x/16 C) x/20 D) 3x/40 E) 3x/80

Solution: Just plugging in values   X= 200   Cost per person if we consider 10 = 20   Cost per person if we consider 20 = 10   Difference between costs is 10 dollars.   Plugging in the value of x into the answer choices, let's see which one yields a result of 10. And that is x/20.

A certain club has 10 members, including Harry. One of the 10 members is to be chosen at random to be the president, one of the remaining 9 members is to be chosen at random to be the secretary, and one of the remaining 8 members is to be chosen at random to be the treasurer. What is the probability that Harry will be either the member chosen to be the president or the member chosen to be the treasurer?	Choose the correct choice from the following:
A) 1/720	B) 1/80	C) 2/10	D) 1/9	E) 1/6

Solution: This question is much easier than it appears.   Each member out of 10, including Harry, has equal chances to be selected for any of the positions (the sequence of the selection is given just to confuse us). The probability that Harry will be selected to be the president is 1/10 and the probability that Harry will be selected to be the treasurer is also 1/10. So, the probability that Harry will be selected to be either the president or the the treasurer is 1/10+1/10=2/10.   Answer: 2/10

A parking garage rents parking spaces for $12 per week or $30 per month. How much does a person save in a year by renting by the month rather than by the week?  Choose the correct choice from the following choices:
A) $140 B) $160 C) $220 D) $240 E) $264

Solution: 12$ per week!   An year has 52 weeks.   Annual charges per year = 52* 12= 
52* 12 = 624
624$   30$ per month!   An year has 12 months.   Annual charges per year= 12 * 30= 
12 * 30 = 360
360$    624 - 360= 
 624 - 360 = 264
264   Ans $264
