There are 35 students in a hostel. If the no. of students increases by 11, the expenses of the mess increase by Rs.42/day while the average expenditure per head diminishes by Rs1. Find the original expenditure of the mess?	Answers:
A) 238 B) 240 C) 242 D) 245 E) 280

Solution: Suppose the average join the mess , total expenditure = 35x + 42   Now, the average expenditure = (35x + 42)/ (35 + 11) = x – 1   or, 35x + 42 = 46x – 46   or, x = 8   Thus the original expenditure of the mess = 35 x 8 = Rs. 280   280

Find the number which is nearest to 3105 and is exactly divisible by 21.	Select the correct option
A) 1208 B) 3108 C) 241 D) 217 E) 3147

Solution: Sol. On dividing 3105 by 21, we get 18 as remainder.   Number to be added to 3105 = (21 - 18) - 3.   Hence, required number = 3105 + 3= 
3105 + 3 = 3_108

Answer: B
Raj is working on a set of Data Sufficiency problems for his December GMAT: a geometry problem, an algebra problem, and a data interpretation problem. He has determined that statement 1 of the geometry problem is insufficient on its own, that both statement 1 and 2 of the algebra problem are insufficient on their own, and that statement 2 of the data interpretation problem is insufficient on its own. If the probabilities are expressed as percents Q, approximately how much greater is the probability that all three answers are “C” after Raj figures out that statement 1 of the data interpretation problem is also insufficient on its own?  Choose one
A) Q=2.3%  B) Q=2.8%  C) Q=3.3%  D) Q=5.6%  E) Q=8.3%

Solution: Step 1: Figure out what we need to know.We have two probabilities that we need to figure out: the one before Raj figures out that statement 1 of the data interpretation problem is also insufficient, and the one after. The answer is the difference between them, in the form of a percent.   Step 2: The first probability.   If statement 1 of the geometry problem is insufficient, then the only valid answer choices are B, C, and E; the probability that it is C is 1/3.   If both statements of the algebra problem are insufficient on their own, then the only remaining valid answers are C and E; the probability that it is C is 1/2   If statement 2 of the data interpretation problem is insufficient, then the remaining answers are A, C, and E, and the probability that C is correct is 1/3.   The probability of all three occurring is the product of the probability fractions: (1/3)*(1/2)*(1/3) = 1/18.   Step 3: The second probability.   Only the third problem has changed; if Raj now knows that statement 1 is also insufficient, the valid answer choices are only C and E, leaving a 1/2 probability that the answer is C.   The probability of all three occurring is still the product of those fractions, but this time they are (1/3)*(1/2)*(1/2) = 1/12.   Step 4: The answer.Note that here, as will sometimes happen on the GMAT, values that you compute “along the way” appear as wrong answer choices. This problem calls for the difference between our two numbers,Q (1/12)-(1/18) = 1/36, which is a 2.77777% chance, rounded to 2.8% —the correct answer is Choice Q=2.8%.

6 friends visited a book stall and brought 6 books, and everyone decided to contribute equally to the total bill of $400. If one of the friends had a coupon for 5% off the total bill, and if each friend still contributed equally after the coupon was applied to the bill, how much did each friend pay? Pick:
A) 62.12
B) 63
C) 63.33
D) 64
E) 65

Solution: At the non-discounted price, each friend would pay $66.66, as $400 divided by 6 friends is $66.66 per friend. But if the bill is 5% off, then each friend would pay 5% less. 5% of $66.66 is $3.33, so each friend saves $3.33 and pays the remaining $63.33   63.33ORRE63.33T OPTION:OPTION 63.33

D) 3/2
E) 3

Solution: I also soved it, but a bit differently. Thank you for reminding me of this much easier and logical way!   What I did was to test powers of 3 that would lead to 9.   So, we have 3 raised to the same power 3 times and 9 raised to another power one time: 3^m3^m3^m = 9^n   What I did was test 3 raised to the power of 2 like this:   3^2*3^2*3^2 = 9*9*9 = 9^3. This means that m=2 and n=3. So, m/n=1/3.1/3

In N is a positive integer less than 200, and 14N/60 is an integer, then N has how many different positive prime factors A?
Choose the correct choice from the following answers
A) 2 B) 3 C) 5 D) 6 E) 8

Solution: I like to put the numbers in prime factors so it is easier and faster to visualize.   14*n/60   If we write the factors of 14 --> 2, 7, and the factors of 60 --> 2, 2, 3, 5, we have   (2*7*n)/(2^2*3*5)   Simplifying   7*n/(2*3*5)   The only way the equation above has an integer value is if n has AT LEAST the factors 2, 3 and 5, so we can simplify again and we have the number 7.   The number could be 2*3*5, or 2*3*5*2, or 2*3*5*.....   However to be less than 200 we can not add any prime number.   2*3*5 = 120   If we added the next prime factor 7, we would have A=2*3*5*7 = 840   Thus, answer 3

A rectangular room has the rectangular shaped rug shown as above figure such that the rug’s area is 180 square feet and its length is 8 feet longer than its width. If the uniform width between the rug and room is 8 feet, what is the area of the region uncovered by the rug (shaded region), in square feet?
Answers:
A) 32
B) 36
C) 704
D) 46
E) 104

Solution: Rug's area = 180   which is (x) x (8+x) = 180   so x= 10   rug maintains a uniform distance of 8 feet   so room has dimension 10+16 and 18+16 i.e. 26 and 34   area of room 26x34 = 884 area covered is 180   so uncovered area is 884-180= 
884-180 = 704

Answer: C
Gita, Hussain, Inge, Jeong, Karen, and Leila are seated in a row of six chairs. How many seating arrangements are possible if Gita cannot sit next to Inge and Jeong must sit next to Leila?  Options
A) 288	B) 240	C) 144	D) 120	E) 96

Solution: taking he initials of each for reference... Since, J and L have to be together, lets combine them into 1. So, now we have 5 things which can be arranged in 5! ways. ALso, J and L can be arranged in two ways (JL, LJ) .   This gives total ways, 5! * 2 = 240   Now, we are given G and I can not be together, therefore subtract the cases when they (G and I) are together. Now, see we have 4 people (JL and GI) are combined as one. Total no of arrangement = 4!   But, J and L can be arranged internally in 2 ways (JL and LJ). Similarly, G and I can be internally arranged in two ways (GI and IG).   Therefore, total such cases will be 4! * 2 * 2 = 96. Subtract this from 240.   240 - 96= 
240 - 96 = 144
144. Hence, 144

Answer: D
Anna left for city A from city B at 5.20 a.m. She traveled at the speed of 80 km/hr for 2 hrs 15 min. After that the speed was reduced to 60 km/hr. If the distance between two cities is 350 kms, at what time did Anna reach city A? Choose the correct choice from the following answers.
A) 10.21
B) 10.27
C) 10.25
D) 10.23
E) 60.25

Solution: Distance covered in 2 hrs 15 min i.e., 2 1/4 hrs = 80 * 9/4= 
80 * 9/4 = 180
180 hrs.   Time taken to cover remaining distance= (350 - 180)/60 = 17/6 hrs   = 2 5/6 = 2 hrs 50 min   Total time taken = (2 hrs 15 min + 2 hrs 50 min) = 5 hrs 5 min.   So, Anna reached city A at 10.25 a.m.   Answer: 60.25
Answer: E
