How many 9 digit numbers are possible by using the digits 1,2,3,4,5 which are divisible by 4 if the repetition is allowed?  Answers:
A) 56  B) 57  C) 55  D) 59  E) 58

Solution: _ _ _ _ _ _ _ _ _ (9 digit number)   Digits that can be used = 1, 2, 3, 4 and 5   For a number to divisible by 4, the last two digits have to be divisible by 4   So, the units digit cannot be 1, 3 or 5   If the units digit is 2, only 12, 32 adn 52 are acceptable as the last two digits   If the units digit is 4, only 24 and 44 are acceptable as the last two digits.   So, total 5 cases for the last two digits.   Now, the first 7 digits of the 9 digit number can be filled in 57 ways as each place can be filled by 1, 2, 3, 4 or 5.   So, desired answer = 57*5 = 58   ANSW58R:58

A tank holds x gallons of a saltwater solution that is 20% salt by volume. One Fourth of the water is evaporated, leaving all of the salt. When 10 Gallons of water and 20 gallons of salt are added, the resulting mixture is 33 1/3 % salt by volume. What is the value of x?
Options
A) 37.5 B) 75 C) 100 D) 150 E) 175

Solution: Original mixture has 20% salt and 80% water.   Total = x   Out of which Salt = 0.2x and water = 0.8x   Now, 1/4 water evaporates and all salt remains.   So what remains is 0.2x salt and 0.6x water.   Now 20 gallons salt is added and 10 gallons of water is added.   So salt now becomes -> (0.2x + 20) and water --> (0.6x+10)   Amount of salt is 33.33% of total. So amount of water is 66.66%. So salt is half of the volume of water.   So (0.2x+20) = (0.6x+10)/2,   Solving, x = 150.   ANSWER:150

A) 3  B) 4  C) 5  D) 6  E) 7

Solution: we can take numbers, as price of car 5, 8 for train and 31 total for ease.   Now we can determine quickly that total number should range between 31/8 <= N <=31/5 , so ans should be between 3 and 7.   Now solving the expression 5A+8B =31   decreasing 31 in multiple of 5 and checking divisibility of that number by 8. this way we get   3 cars, 2 trains we get $31.00 total  3*5 + 2*8=

Answer: A
Two trains A and B starting from two points and travelling in opposite directions, reach their destinations 9 hours and 4 hours respectively after meeting each other. If the train A travels at 90kmph, find the rate at which the train B runs.  Select the correct option: A) 40 B) 60 C) 135 D) 80 E) 100

Solution: If two objects A and B start simultaneously from opposite points and, after meeting, reach their destinations in ‘a’ and ‘b’ hours respectively (i.e. A takes ‘a hrs’ to travel from the meeting point to his destination and B takes ‘b hrs’ to travel from the meeting point to his destination), then the ratio of their speeds is given by:   Sa/Sb = √(b/a)   i.e. Ratio of speeds is given by the square root of the inverse ratio of time taken.   Sa/Sb = √(4/9) = 2/3   This gives us that the ratio of the speed of A : speed of B as 2:3.   Since speed of A is 80 kmph, speed of B must be 80*(3/2) = 135 kmph   135

Answer: B
Grace packed 5 pairs of shoes, 3 pairs of pants, 8 shirts, and 3 jackets for her business trip. If an outfit consists of one of each item of clothing except shirts, of which she will wear 2, how many different outfits can does Grace have available during her trip?
Select the correct option.
A) 2,520	B) 1,260	C) 620	D) 360	E) 120

Solution: the number of possibilities for each item of clothing with the different items. For the shirts you essentially choose 2 out of 8 so you should use the combination formula (don't know how to use math symbols here).   This gives you 5 x 3 x 28 x 3 = 1'260. Hence, solution 1,260 is correct.
Answer: B
Which of the following is equal to 3.14 x 10(power 6) ?  Choose one
A) 31400.0  B) 3140000  C) 3140.0  D) 314.0  E) None of them

Solution: = 3.14 x 10(power 6)   = 3.14 x 1000000   = 3140000.   Answer is 3140000.
Answer: B
A can contains a mixture of two liquids A and B is the ratio 7 : 5. When 9 litres of mixture are drawn off and the can is filled with B, the ratio of A and B becomes 7 : 9. How many litres of liquid A was contained by the can initially? Choose one:  A) 10  B) 20  C) 21  D) 25  E) 24

Solution: Explanation:   Suppose the can initially contains 7x and 5x of mixtures A and B respectively.   Quantity of A in mixture left =(7x-7/12 x9)litres =(7x -21/4)litres .   Quantity of B in mixture left =(5x-5/12 x9)litres =(5x -15/4)litres .   (7x -21/4) / (5x -15/4) +9 = 7/9   28x - 21 /20x + 21 = 7/9   252x - 189 = 140x + 147   112x = 336   x = 3.   So, the can contained 21 litres of A.   ANSWER IS 21
Answer: C
The average age of father and his two sons is 22 Years. Five years ago, the average age of the two sons was 19 Years. If the difference between the ages of the two sons is four years, what is the present age of the father? Choose the correct choice:	A) 18	B) 46	C) 47	D) 48	E) 49

Solution: The total present age of father and two sons is 3x22 = 66 yrs   The total present age of sons is (19+5) X 2 = 48Years   so, present age of father is 66 â€“ 48 = 18 yrs   18nswer 18
Answer: A
If a boat goes 9km upstream in 108 minutes and the speed of the stream is 2 kmph, then the speed of the boat in still water is ?
Choose the correct choice from the following options:
A) 5
B) 6
C) 7
D) 8
E) 9

Solution: Rate upsteram =(9/108*60)= 
(9/108*60) = 5
5kmph.   speed of the stream=2kmph let speed in still water be xkm/hr. then speed upstream=(x-2)km/hr. x-2=5==>x=7km/hr Answer(7)

A batsman scored 120 runs which included 3 boundaries and 8 sixes. What percent of his total score did he make by running between the wickets ?  Choose one:
A) 33	B) 39	C) 50	D) 29	E) 28

Solution: Explanation:   Number of runs made by running = 120 - (3*4 + 8*6)   = 120 - (60)= 
120 - (60) = 60
60   Required percentage= \inline (\frac{60}{120}\times 100) % = 50%   Answer: 50) 50%

A sum of money at simple interest amounts to Rs. 815 in 3 years and to Rs. 854 in 4 years. The sum is?	Pick one
A) 688
B) 798
C) 698
D) 699
E) 998

Solution: S.I. for 1 year = Rs. (854 - 815) = Rs. 39.   S.I. for 3 years = Rs.(39 x 3) = Rs. 117.   Principal = Rs. (815 - 117) = Rs. 698.   Answer:698
Answer: C
