An investment of d dollars at k percent simple annual interest yields $600 over a 2 year period. In terms of d, what dollar amount invested at the same rate will yield $2,400 over a 3 year period?  Choose the correct option:	A) (2d)/3	B) (3d)/4	C) (4d)/3	D) (3d)/2	E) (8d)/3

Solution: 600 dollars in 2 years means 300 dollars in 1 year.   To get 2400 dollars' it will take 8 years.   To get 2400 in 3 years, we need 8/3 times money.   Answer is (8d)/3.

A train moves fast a telegraph post and a bridge 264 m long in 8 sec and 20 sec respectively. What is the speed of the train? Choose the correct option:
A) 78	B) 77	C) 76	D) 79.2	E) 75

Solution: Let the length of the train be x m and its speed be y m/sec.   Then, x/y = 8 => x = 8y   (x + 264)/20 = y   y = 22   Speed = 22 m/sec = 22 * 18/5= 
22 * 18/5 = 396/5 = around 79.2
79.2 km/hr.   Answer: Option 79.2

Answer: B
An officers identification code consists of a vowel followed by a 3-digit number greater than 200. Exactly 2 of the 3 digits in the code should be identical. How many different codes is it possible to form? Choose one
A) 211
B) 216
C) 1075
D) 1080
E) 2160

Solution: An officers identification code will be of the type -,-,-,-   first digit can be selected from any of the 5 vowels in 5C1 ways   now for the remaining three digit lets consider the following two cases   case 1: when the number is greater than 200 but less than 300   number will be of the type 2,_,_. now suppose repeating number is same as first digit number i.e. 2. and the third number is one of the remaining 9 numbers (we are rejecting 2 here, because it will result in 222, which is not acceptable as per the given condition). thus these two number can arrange themselves in two blank spaces in 2! ways. hence total number of numbers in which repeating digit is same as the first digit = 1.9.2! =18   now, suppose that repeating number is different than first digit. thus possible case in this case are 8 as listed below:   211   233   244   255   266   277   288   299   here again we have rejected 200( because number must be greater than 200) and 222 ( exactly two repeating digits are allowed)   thus total possible cases are 18 + 8= 
18 + 8 = 26
26   case 2: number ranging from 300 to 999   here for first digit we have 7 cases (3,4,5,6,7,8,9)   now if the repeating number is same as the first number then we will have 18 cases ( same reasoning as mentioned in the previous case)   if the repeating number is different than first digit number then we will have 9 cases ( because here number ending with two zeros are allowed)   hence total number of ways= 7(18+9) = 189   thus different number of codes = 5(189+26) = 1075   hence 1075

A car drove from Town A to Town B without stopping. The car traveled the first 60 miles of its journey at an average speed of 25 miles per hour. What was the car’s average speed, in miles per hour, for the remaining 100 miles if the car’s average speed for the entire trip was 40 miles per hour?  Options:
A) 28.5	B) 48.5	C) 50.4	D) 55.5	E) 62.5

Solution: KAPLAN OFFICIAL SOLUTION:   To solve this problem, you must remember that average speed means total distance divided by total time over an entire journey. This should not be confused with the average of the speeds. The total distance in this problem is 160 miles, but we will need to express the total time in a more complex way.   For the first 60 miles, the car traveled at 25 miles per hour. Therefore, we can say that the time this took was 60/25, because distance divided by rate equals time.   For the last 100 miles, we are trying to solve for the rate, so we can call this speed R. Thus, the time for the final 100 miles is 100/R.   If we put all of this together, knowing that the average speed over the entire journey is 40 miles per hour, we get the equation 160/(60/25 + 100/R) = 40. We can now solve for R and reach our answer.   160/(60/25 + 100/R) = 40   R = 62.5   50 is choice (62.5) and that’s our correct answer.

For any number y, y* is defined as the greatest positive even integer less than or equal to y. What is the value of 9.2 – 9.2*?	Select the correct option:
A) 0.2
B) 1.2
C) 1.8
D) 2.2
E) 4.0

Solution: Since y* is defined as the greatest positive even integer less than or equal to y, then 9.2* = 8 (the greatest positive even integer less than or equal to 9.2 is 4).   Hence, 9.2 – 9.2* = 9.2 - 8=

An investor bought 200 shares of stock in ABCD company in 1990. By 1992, the investment was worth only 2/3 of its original value. By 1995, the 200 shares were worth only 3/5 of their value in 1990. By what percent did the value of the investment drop from 1992 to 1995?	Choose the most appropriate option.
A) 16 2/3%	B) 25%	C) 33 1/3%	D) 50%	E) 10%

Solution: Let price of each share in 1990 = X.   Total cost in 1990 = 200X   Now Price in 1992 = 2/3 * 200X = 400/3 * X   Now price in 1995 = 3/5 *200= 
3/5 *200 = 120
120X   %Change in 1995 from 1992= [(400/3* X -120X) / (400/3 *X) ] *100 = 10%   Answer 10%
Answer: E
For any integer m greater than 1, $m denotes the product of all the integers from 1 to m, inclusive. How many prime numbers are there between $7 + 2 and $7 + 10, inclusive?
Choose the correct option.
A) None  B) One  C) Two  D) Three  E) Four

Solution: $ is basically a factorial of a number.   So, we are asked to find the number of primes between 7!+2 and 7!+10, inclusive.   From each number 7!+k were 2≤k≤102≤k≤10 we can factor out k, thus there are no pries in the given range.   For example:   7!+2=2(3*4*5*6*7+1) --> a multiple of 2, thus not a prime;   7!+3=3(2*4*5*6*7+1) --> a multiple of 3, thus not a prime;   ...   7!+10=10(3*4*6*7+1) --> a multiple of 10, thus not a prime.   Nonenswer: None.
