Company KW is being sold, and both Company A and Company B were considering the purchase. The price of Company KW is 20% more than Company A has in assets, and this same price is also 100% more than Company B has in assets. If Companies A and B were to merge and combine their assets, the price of Company KW would be approximately what percent of these combined assets?  Choose the most appropriate option:
A) 66%  B) 75%  C) 86%  D) 116%  E) 150%

Solution: Let the price of Company A's assets be 100   Price of assets of KW is 20% more than company A's assets which is 120   Price of assets of KW is 100% more than company 75%'s assets which means price of Company 75%'s assets is half the price of KW = 60   A+75% = 160   KW = 120   KW/(A+75%)*100 = 120/160*100= 
120/160*100 = 75

Bob travels at an average speed of 12km/h, to the school and then return to the home he travels at an average speed of 10km/h. Which of the following is the closest approximation of Bob's average speed, in kilometers per hour, for the trip? Select
A) 6.3 B) 2.9 C) 15.2 D) 10.9 E) 9.1

Solution: Since we're not given a distance to work with, we can TEST any distance that we like. Here, since the speeds are 12 km/hour and 10 km/hour, using a multiple of both 12 and 10 would make the math easiest.   Let's set the Distance up the hill at 60 km.   So, going school, we have....   D = (R)(T)   60 = (5)(T)   60/12= 
60/12 = 5
5= T   5 hours to go school   Going home, we have....   10.9 = (R)(T)   60 = (10)(T)   60/10= 
60/10 = 6
6= T   6 hours to go home   Total 10.9istance = 120 km   Total Time = 5+6= 
5+6 = 11
11 hours   Average Speed= 120/11 = 10.9 km/hour   10.9

Jane covered a distance of 320 miles between city A and city B taking a total of 5 hours. If part of the distance was covered at 60 miles per hour speed and the balance at 80 miles per hour speed, how many hours did she travel at 60 miles per hour?  Choose the most appropriate option.
A) 2 hours 30 minutes
B) 3 hours
C) 2 hours
D) 1 hour 45 minutes
E) None of these

Solution: Answer   Let Jane travel 'x' at 60 miles per hour.   As the total time taken to cover 340 miles is 5 hours, Jane would have traveled (5 - x) hours at 80 miles per hour.   Distance covered at 60 miles per hour = Speed * time = 60 * x = 60x miles.   Distance covered at 80 miles per hour = Speed * time = 80 (5 - x) = 400 - 80x miles.   Total distance covered = Distance covered at 60 miles per hour + Distance covered at 80 miles per hour.   Therefore, total distance = 60x + 400 - 80x.   Total distance travelled = 340 miles.   Therefore, 320 = 60x + 400 - 80x   20x = 40 or x = 2 hours.   2 hourshoice 2 hours

A train has a length of 150 meters . it is passing a man who is moving at 5 km/hr in the same direction of the train, in 3 seconds. Find out the speed of the train.
Answers
A) 182 km/hr B) 180 km/hr C) 185 km/hr D) 169 km/hr E) 179 km/hr

Solution: Explanation:   Length of the train, l = 150m   Speed of the man , Vm= 5 km/hr   Relative speed, Vr = total distance/time = (150/3) m/s = (150/3) × (18/5) = 180 km/hr   Relative Speed = Speed of train, Vt - Speed of man (As both are moving in the same direction)   => 180 = Vt - 5   => Vt = 180 + 5= 
180 + 5 = 185
185 km/hr   Answer: Option 185 km/hr

A set of numbers has the property that for any number t in the set, t + 2 is in the set. If -1 is in the set, which of the following must also be in the set?
I. 5
II. 1
III. -4	Choose the most appropriate option:
A) I only  B) II only  C) I and II only  D) II and III only  E) I, II, and III

Solution: The question is which of the following must be in the set, not could be in the set.   If -1 is in the set so must be   -1+2= 
  -1+2 = 1
1, as 1 is in the set so must be   1+2= 
  1+2 = 3
3, as 3 is in the set so must be   3+2= 
  3+2 = 5
5 and so on. So basically knowing that -1 is in the set we can say that ALL odd numbers more than -1 are also in the set.   Answer: I and II only.

A) III only
B) I only
C) II only
D) I,II only
E) I,II and III

Solution: Given: x and y are different prime numbers, both greater than 10   Statement I: x+y is an even integer   Since x and y are prime numbers greater than 10, they will be odd   Therefore sum will be even.   Correct   Statement II: xy is an odd integer   Since x and y are prime numbers greater than 10, they will be odd   Therefore multiplication will be odd.   Correct   Statement III: (x/y) is not an integer   Since x and y are prime integers, therefore they will not have any common factor apart from 1   Hence (x/y) will not be an integer   Correct   Hence all three statements I, II and III are correct   Answer : I,II and III

A password for a computer uses three digits from 0 to 9, inclusive. What is the probability that the digits of the password solely consist of prime numbers or zero?
Choose the correct answer:
A) 1/32
B) 1/16
C) 1/8
D) 2/5
E) 1/2

Solution: To calculate all the possibilities, there are 10 choices for each digit. The number of possibilities for five digits is 10 × 10 × 10 = 1,000 possible combinations.   Prime numbers constitute 2, 3 In addition to zero, this is 3 total possibility for each digit. So the number of satisfactory variants is 3× 3 × 3 . So the probability is 1/2 × 1/2 × 1/2 = 1/8.   The right answer is choice (1/8).
