Pick one:
A) 162
B) 108
C) 96
D) 54
E) None

Solution: Solution: Let the number of students in the classes be 2x, 3x and 4x respectively;   Total students = 2x+3x+4x = 9x.   According to the question,   (2x+12)/(3x+12) 2 +3 +4= 
2 +3 +4 = 9
9x.   According to the question,   (2x+12)/(3x+12)= 8/11   24x+96 = 22x+132   Or, 2x = 132-96   Or, x = 36/2= 
36/2 = 18
18   Hence, Original number of students,   9x= 9*18= 
9*18 = 162

Answer: B
A line has a slope of 3/4 and intersects the point (-12, -39). At which point E does this line intersect the x-axis?  Select the correct option:
A) (40,0)  B) (30,0)  C) (0,40)  D) (40,30)  E) (0,30)

Solution: Assume that the equation of the line is y=mx+c, where m and c are the slope and y-intercept.   You are also given that the line crosses the point (-12,-39), this means that this point will also lie on the line above.   Thus you get -39=m*(-12)+c , with m=3/4 as the slope is given to be 3/4.   After substituting the above values, you get c = -30.   Thus the equation of the line is y=0.75*x-30 and the point where it will intersect the x-axis will be with y coordinate = 0.   Put y=0 in the above equation of the line and you will get, x=40.   Thus, the point E of intersection is (40,0).   (40,0) is the correct answer.

There can be myriad ways to create a palindrome. One day, I thought of making my own palindrome. I thought of a number and then decided to add the reversed number to it. Sadly, I did not get a palindrome.
So I kept repeating this step and eventually I succeeded in creating a palindrome. I don't know if you can always create a palindrome using this method but I was able to generate one of four digits.
Can you tell me the number at which I started?  Choose the correct answer.
A) 192	B) 130	C) 185	D) 167	E) 120

Therefore, required number of non-negative integers is equal to count of numbers less than 10,000 which are divisible by 3.   Such numbers are (3, 6, 9, ... , 9999) (arithmetic progression with first term=3, last term=9999, common difference=3).   Count of such numbers =   9999   3   =   3333   99993=3333   But zero is also divisible by 3.   This makes our total count 3334   3334

The sum of all two digit numbers divisible by 6 is Select the correct option: A) 910 B) 510 C) 710 D) 610 E) 810

Solution: Required numbers are 12,18,24 . . . . . 96   This is an A.P. in which a=12,d=6 and l=96.   Let the number of terms in it be n.Then t=96   So a+(n-1)d=96.   12+(n-1)*6=96,   12+6n-6=96   6+6n=96   6n=96-6= 
96-6 = 90
90/6= 
90/6 = 15
15.   Required sum=n/2(a+l)   =15/2(12+96)   =810   Answer is 810.

Jim bought edging to go around a circular garden with a radius of 3 feet. Later he decided to
double the diameter of the garden. How many more feet of edging must he buy?	Choose the correct choice from the following answers:
A) 28.84' additional edging
B) 48.84' additional edging
C) 38.84' additional edging
D) 18.84' additional edging
E) 58.84' additional edging

Solution: (2)3.14 x 3 = 18.84' circumference of small garden   2 x 3 = 6' diameter of small garden   3.14 x 12 = 37.68' circumference of garden with   doubled diameter    37.68 - 18.84= 
 37.68 - 18.84 = 18.84
18.84' additional edging needed   In real life this would probably be rounded to 19 or 20 feet.   correct answer 18.84' additional edging

Answer: E
Exactly 3/5 of the people in the room are under the age of 21, and exactly 5/13 of the people in the room are over the age of 65. If the total number of the people in the room is greater than 50 and less than 100, how many people in the room are under the age of 21?
Answers
A) 21
B) 35
C) 39
D) 60
E) 42

Solution: The total number of the people in the room must be a multiple of both 5 and 14 (in order 3/5 and 5/14 of the number to be an integer), thus the total number of the people must be a multiple of LCM of 5 and 14, which is 70.   Since, the total number of the people in the room is greater than 50 and less than 100, then there are 70 people in the room.   Therefore there are   3/5*70= 
  3/5*70 = 42
42 people in the room under the age of 21.   Answer: 42.
