Sarah is driving to the airport. After driving at 25 miles per hour for one hour, she realizes that if she continues at that same average rate she will be an hour late for her flight. She then travels 50 miles per hour for the rest of the trip, and arrives 30 minutes before her flight departs. How many miles did she drive in all? Options.
A) 100
B) 175
C) 210
D) 245
E) 280

Solution: After driving at 25 miles per hourfor one hour, this distance left to cover is d-25. Say this distance is x miles.   Now, we know that the difference in time between covering this distance at 25 miles per hour and 50 miles per hour is 1+ 1/2 = 3/2 hours.   So, we have that x/25 - x/50 = 3/2 --> 2x/50 - x/50 = 3/2 --> x/50 = 3/2 --> x = 75.   Total distance = x + 25 = 100 miles.   100nswer:100

12 men take 36 days to do a work while 12 women complete 3/4th of the same work in 36 days. In how many days 10 men and 8 women together will complete the same work?
Choose the correct choice from the following choices
A) 6 days
B) 12 days
C) 27 days
D) 28 days
E) None of these

Solution: Explanation:   1 man’s 1 day’s work = 1/ 36 × 12 = 1/432   10 men’s 1 day’s work = 10/432   12 women can finish the whole work in 4 × 36/3 = 48 days   1 woman’s 1 days work = 1/ 48 × 12 = 1/576   8 women’s 1 day’s work = 8/572 = 1/72   (10 men + 8 women)’s 1 day’s work = 10/432 + 1/72 = 10 + 6/432 = 16/432   = 1/27   Therefore, the required No. of days = 27 days.   Answer: Option 27 days

x^2 + sx + 72 = 0 has two distinct integer roots; how many values are possible for s?	Choices
A) 3  B) 6  C) 8  D) 12  E) 24

Solution: For a quadratic equation ax^2+sx+c=0, we know that -s/a is sum of roots and c/a is product of roots.   The quadratic equation here is x^2 + sx + 72 = 0, where product of roots is 72.   If we find all the factors of 72, we have the answer.   By prime factorization, we get 72= 2^3*3^2.   We know that total factors are  (3+1)*(2+1)= 
 (3+1)*(2+1) = 12

Murphy and Cooper are having the same amount of petrol in the petrol tanks of their respective cars. Murphy can drive for four hours with that amount whole Cooper can drive for five hours.
They both starts together and keep driving for a few hours. After some time, they find that the amount of petrol remaining in one car is four times that of the other car.
Using all these facts, can you find out how long they drove their cars?	Select.
A) 2 3/4 hours.
B) 3 3/4 hours.
C) 4 3/4 hours.
D) 5 3/4 hours.
E) 6 3/4 hours.

Solution: Solution:   3 3/4 hours   Explanation:   Suppose that the amount of petrol in each of the cars in the beginning was M.   Now, suppose that they drove for X hours.   In that case, the amount of petrol used by one car in X hours will be = M*X /4   The amount of petrol used by the other car will be = M*X/5   Therefore, the petrol left in one car = M - M*X / 4   Petrol left in the other car = M - M*X / 5   Now, according to the question,   M - M*X / 5 = 4 (M - M*X / 4)   => X = 15 / 4 = 3 3/4 hours.   Therefore Murphy and Cooper drove for 3 3/4 hours.   Answer 3 3/4 hours.

Choices:
A) 11	B) 12	C) 13	D) 14	E) 15

Solution: Forget conventional ways of solving math questions. In PS, IVY approach is the easiest and quickest way to find the answer.   the sum of the squares of the first 4 positive integers = 1^2 + 2^2 + 3^2 +4^2+5^2 = 55   the sum of the prime numbers between the first square(=1) and fourth square(=16) = 2+3+5+7+11+13= 
2+3+5+7+11+13 = 41
41.   So the difference between 41 and 55 is 14.   So the answer is (14).

D) 13.9
E) 14.2

Solution: Let x be the factor by which the bacteria increases every three hours.   At 4:00 pm, the amount of bacteria was 10x and at 7:00 pm it was 10x^2.   10x^2 = 16.9   x^2=1.69   x=1.3   At 4:00 pm, the amount of bacteria was 10(1.3)=13 grams.   The answer is 13.0.
Answer: A
In a certain Gun shooting competition prizes were awarded as follows: the first place winner receives 11 points, the second place winner receives 7 points, the third place winner receives 5 points and the fourth place winner receives 2 points .

A) 7
B) 5
C) 3
D) 2
E) cannot be determined

Solution: 84700 = 2*2*5*5*7*11*11   If the question stated that John atleast came 4th each time he participated, then we can say that John participated 7 times.   But, it is not stated how many times did John come fifth, sixth, seventh, etc.   Hence, Answer will be cannot be determined.
Answer: E
If each of 3 digit code is formed of integers from 1 to 25, inclusively, and each of the digits are different, how many possible codes are there?  Choose the correct choice from the following choices:	A) 13600	B) 13500	C) 13400	D) 13800	E) 13900

Solution: Code consists of 3 digits and no digit is repeated.   First digit of the code can have 25 possibilities   Second digit can have 24 possibilities   Third digit can have 23 possibilities   Total number of possible codes = 25*24*23= 
25*24*23 = 13_800
13800   Answer: 13800
Answer: D
The area of the square formed on the diagonal of a rectangle as its side is 108 1/3 % more than the area of the rectangle. If the perimeter of the rectangle is 28 units, find the difference between the sides of the rectangle?  Options
A) 3	B) 4	C) 5	D) 2	E) 7

Solution: Let the sides of the rectangle be l and b respectively.   From the given data,   (√l2 + b2) = (1 + 108 1/3 %)lb   => l2 + b2 = (1 + 325/3 * 1/100)lb   = (1 + 13/12)lb   = 25/12 lb   => (l2 + b2)/lb = 25/12   12(l2 + b2) = 25lb   Adding 24lb on both sides   12l2 + 12b2 + 24lb = 49lb   12(l2 + b2 + 2lb) = 49lb   but 2(l + b) = 28 => l + b = 14   12(l + b)2 = 49lb   => 12(14)2 = 49lb   => lb = 48   Since l + b = 14, l = 8 and b = 6   l - b = 8 - 6= 
8 - 6 = 2

Answer: D
On a certain day, orangeade was made by mixing a certain amount of orange juice with an equal amount of water. On the next day, orangeade was made by mixing the same amount of orange juice with twice the amount of water. On both days, all the orangeade that was made was sold. If the revenue from selling the orangeade was the same for both days and if the orangeade was sold at $0.82 per glass on the first day, what was the price per glass on the second day?
Choose the correct option:	A) $015	B) $0.20	C) $0.30	D) $0.40	E) $0.55

Solution: On the first day 1 unit of orange juice and 1 unit of water was used to make 2 units of orangeade;   On the second day 1 unit of orange juice and 2 units of water was used to make 3 units of orangeade;   So, the ratio of the amount of orangeade made on the first day to the amount of orangeade made on the second day is 2 to 3. Naturally the ratio of the # of glasses of orangeade made on the first day to the # of glasses of orangeade made on the second day is 2 to 3.   We are told thatthe revenue from selling the orangeade was the same for both daysso the revenue from 2 glasses on the first day equals to the revenue from 3 glasses on the second day.   Say the price of the glass of the orangeade on the second day was $x then 2*0.82=3*x --> x=$0.55.   Answer: $0.55.
Answer: E
A car starts 2/5 of a mile behind a bus that is traveling at 60 miles per hour. If the car catches up to the bus after 2 minutes, how many miles does the car travel in that time?	Pick one
A) 2 1/10	B) 2 2/5	C) 2 1/2	D) 2 7/8	E) 3

Solution: Car is travelling at a speed of 2/5 miles per 2 mins faster than the bus   i.e 12 mph faster than the buse   = 72 mph   So in 2 mins = 72 * 2/60= 
72 * 2/60 = 12/5 = around 2.4
2.4   Answer is 2 2/5.
Answer: B
A train is 360 meter long is running at a speed of 45 km/hour. In what time will it pass a bridge of 140 meter length?	Choices: A) 28 seconds B) 27 seconds C) 40 seconds D) 128 seconds E) 18 seconds

Solution: Speed = 45 Km/hr = 45*(5/18) m/sec = 25/2 m/sec   Total distance = 360+140= 
360+140 = 500
500 meter   Time= Distance/speed   = 500 * (2/25)= 
500 * (2/25) = 40
40 seconds   Answer: 40 seconds
