Question: there are sixty markings on a clock, minutes hand was exactly on one of those markings. nine markings away from the minutes hand was hours hand. what could be the time.
A.5:14
B.6:20
C.7:48
D.3:09
Answer: C.7:48
Explanation: given angle diff=9mins
we know
1min=6 deg
therefore 9mins=9*6=54 deg
so the angle diff must be 54 deg
better to go through the options
let us consider
A.5hrs 14mins
find angle
angle traced by hour hand=(5*30)+(14/2)=157
angle traced by minute hand=(14*6)=84
angle diff=157-84=73
similarly for option C.
angle traced by hour hand=(7*30)+(48/2)=234
angle traced by minute hand=(48*6)=288
angle diff=(288-234)=54

Question: In a certain city, 60 percent of the households have cable television, and 50 percent of the households have videocassette recorders. If there are 150,000 households in the city, then the number of households that have both cable television and videocassette recorders could be any number from:
A.15,000 to 75,000 inclusive
B.15,000 to 90,000 inclusive
C.30,000 to 75,000 inclusive
D.60,000 to 90,000 inclusive
Answer: A.15,000 to 75,000 inclusive
Explanation: The maximum percentage with both is 50% which is 75,000 households.
This means that every household with a recorder also has cable television.
The minimum percentage with both is 10% which is 15,000 households.
This means that 40% of households have only recorders but not cable television.
The other 10% of households with recorders have cable television.
The answer is A.
Question: Rohit paid $4,000 for 100 shares of stock X and $2,000 for 100 shares of stock Y. He later sold the same shares of both stocks, gaining 3/5 the amount he paid for stock Y. If the prices he had paid for the stocks had been reversed and everything else remained the same, then the net result would have been:
A.A Gain of 1.4 times as much
B.A Gain of 3 times as much
C.A Gain of 2 times as much
D.A Gain of 1.5 times as much
Answer: C.A Gain of 2 times as much
Explanation: A = 4000; B = 2000; Profit = (3/5)*2000 = 1200
After prices are reversed:
A = 2000; B =4000; Profit = (3/5)*4000 = 2400
2400 --> Gain of 2 times 1200

Question: Of the 60 researchers in a workgroup, 40 percent will be assigned to Team A and the remaining 60 percent to Team B. However, 70 percent of the researchers prefer Team A and 30 percent prefer Team B. What is the lowest possible number of researchers who will NOT be assigned to the team they prefer?
A. 15
B. 18
C. 20
D. 25
Answer: B. 18
Explanation: I solved it by assuming 100 people and then dividing my answer in two to save time on calculations. (percentage equals number of people) In that case
40 will be in team A
60 will be in team B
The larger diff is
70 want team A so diff is 70-40=30. At least 30 people will NOT get their wish, so for 60 researchers the same number is 18.
Answer choice B
Question: Last year the price per share of Stock X increased by k percent and the earnings per share of Stock X increased by m percent, where k is greater than m. By what percent did the ratio of price per share to earnings per share increase, in terms of k and m?
A.k/m %
B.(k – m) %
C.[100(k – m)] / (100 + k) %
D.[100(k – m)] / (100 + m) %
Answer: D.[100(k – m)] / (100 + m) %
Explanation: One way of doing this is assuming some value for y. Say, y = 60. So x is greater than 20 but less than 30. Say x could be 25.
Not put y = 60 and x = 25 in the options:
(A) y < x < 2y -----> 60 < 25 < 2*120 ( does not hold)
(B) 2y < 6x < 3y ------> 2*60 < 6*25 < 3*60 (holds so could be the answer)
Mind you, you need to check every option to ensure that the relation holds for only one option. If it holds for more than one options, you will need to check for some other values too.
The point is that we assume values and then plug them in the options to see which relation works.
Last Year:
Price per share (PPS) increased by k%. Let's say k = 20. So if the price was 100, it increased by 20% to become 120 (New PPS).
Earnings per share increased by m%. Let's say m = 10 (m must be less than k). So if earnings per share was also 100, it increased by 10% to become 110 (New EPS).
By what percent did the ratio of price per share to earnings per share increase?
Ratio of PPS/EPS was 100/100 = 1
New ratio = New PPS/ New EPS = 120/110 = 1.0909
%Increase = [(1.0909 - 1)/1] * 100 = 9.09%
Now, in the options, put k = 20, m = 10
Only (D) will give you 9.09%. Let me show you calculations of some of the options.
B. (k – m) %
(20 - 10)% = 10% (Not the answer)
C. [100(k – m)] / (100 + k) %
[100(20 - 10)]/(100 + 20) % = 1000/120 % = 8.3% (Not the answer)
D. [100(k – m)] / (100 + m) %
[100(20 – 10)] / (100 + 10) % = 1000/11 % = 9.09% (Answer) answer is D

Question: A fair price shopkeeper takes 10% profit on his goods. He lost 20% goods during theft. His loss percent is:
A.72%
B.42%
C.32%
D.12%
Answer: D.12%
Explanation: Explanation:
Suppose he has 100 items. Let C.P. of each item be Re. 1.
Total cost = Rs. 100. Number of items left after theft = 80.
S.P. of each item = Rs. 1.10
Total sale = 1.10 * 80 = Rs. 88
Hence, loss % = 12/100 * 100 = 12%

Question: Tom had 63 apples. He divides all apples evenly among 9 friends. How many apples did Tom give to each of his friends?
A.1
B.2
C.18
D.7
Answer: D.7
Explanation: Total number of apples = 63
There are 9 friends of seats on the bus.
To find how many apples Tom gave to each of his friends, divide the total number of apples by the number of friends.
We get, divide 63 by 9
63 ÷ 9 = 7
Therefore, Tom gives 7 apples to each of his friends.

Question: You play the following game with a friend. You share a pile of chips, and you take turns
removing between one and four chips from the pile. (In particular, at least one chip must be
removed on each turn.) The game ends when the last chip is removed from the pile; the one
who removes it is the loser.
It is your turn, and there are 2014 chips in the pile. How many chips should you remove to
guarantee that you win, assuming you then make the best moves until the game is over?
A.1
B.2
C.3
D.4
Answer: C.3
Explanation: The key to winning this game is that if you leave your opponent with 5k +1 chips,
for any integer k 0, then you win. When your opponent removes r chips, you remove 5-r,
and so there are now 5(k- 1) + 1 chips left, and you keep using this strategy until there is
only one chip left, at which point your opponent takes it and loses.
So, you should take 3 chips to leave 2011 = 5 402 + 1.

Question: A bag contains one rupee, 50 paisa and 10 paisa coins in the ratio of 3:2:1. How many 50 paisa coins are there, if the total number of money in the bag is Rs 820?
A.400 coins
B.40 coins
C.100 coins
D.4100 coins
Answer: A.400 coins
Explanation: Let the number of 100p, 50p and 10p coins be 3x ,2x and x .
The ratio of the values of coins = 100 p: 50p :10 p = 10:5:1
Total amount = (10 x 3x ) + (5 x 2x) +( 1 x x) = 30x+10x+x=41x
The ratio of their values in rupees= 30x:10x:x
Given total amount is Rs 820 => 41x = 820 => x=Rs 20
Total value of 50p coins (in rupees) = 10 x 20 =Rs 200
Total 50 paisa coins are = 200 x 2 = 400 coins

Jansi went out for shopping. She had in her handbag approximately Rs. 15/- in one rupee notes and 20 p. coins. When she returned she had as many one rupee notes as she originally had and as many 20 p. coins as she originally had one rupee notes. She actually came back with about one-third of what she had started out with.
How much did she spend and exactly how much did she have with her when she started out ?
There is nothing to explain here. The driving time there and back is absolutely the same because 90 minutes and 1 hour and 30 minutes are one and the same thing.
This problem is meant for inattentive readers who may think that there is some difference between 90 minutes and 1 hour 30 minutes.
Question: How many positive 5-digit integers have the odd sum R of their digits?
A.9*10^2
B.9*10^3
C.10^4
D.45*10^3
Answer: D.45*10^3
Explanation: We are looking at numbers between 10000 and 99999 both inclusive.
There are 90000 numbers.
Now for
10000 : sum of digits is odd;
10001 :sum of digits is even;
10002 : sum of digits is odd ; so on and so forth. So every alternate number is such that the sum of digit is odd.
(Exception for the above statement :
When it is 10009 the sum is even and for 10010 again the sum is even; But if you look at 10019 :sum is odd; 10020 : sum is odd
and this pattern continues so basically the number of odd sum of digits and even sum of digits are equal)
This means exactly half of the numbers will have odd sum of their digits. i.e 45000

Question: The price of 2 sarees and 4 shirts is Rs. 1600. With the same money one can buy 1 saree and 6 shirts. If one wants to buy 12 shirts, how much shall he have to pay ?
A.Rs. 1200
B.Rs. 2400
C.Rs. 4800
D.Cannot be determined
Answer: B.Rs. 2400
Explanation: Let the price of a saree and a shirt be Rs. x and Rs. y respectively.
Then, 2x + 4y = 1600 .... (i)
and x + 6y = 1600 .... (ii)
Divide equation (i) by 2, we get the below equation.
=> x + 2y = 800. --- (iii)
Now subtract (iii) from (ii)
x + 6y = 1600 (-)
x + 2y = 800
----------------
4y = 800
----------------
Therefore, y = 200.
Now apply value of y in (iii)
=> x + 2 x 200 = 800
=> x + 400 = 800
Therefore x = 400
Solving (i) and (ii) we get x = 400, y = 200.
Cost of 12 shirts = Rs. (12 x 200) = Rs. 2400.
Answer: Option B
Question: What is the 4 digit number in which the 1st digit is 1/3 of the second, the 3rd is the sum of the 1st and 2nd, and the last is three times the second?
A.1100
B.1200
C.1349
D.1400
Answer: C.1349
Explanation: First digit is 1/3 second digit => The numbers can be 1 & 3, 2& 6, 3 & 9.
First + second = third => we can eliminate 3 & 9 since 3 + 9 = 12.
Last is 3 times the second => we can eliminate option 2 & 6 since 3 * 6 = 18.
Hence the number is 1349

Question: The dimensions of a room are 25 feet * 15 feet * 12 feet. What is the cost of white washing the four walls of the room at Rs. 5 per square feet if there is one door of dimensions 6 feet * 3 feet and three windows of dimensions 4 feet * 3 feet each?
A.3887
B.2689
C.2678
D.4530
Answer: D.4530
Explanation: Area of the four walls = 2h(l + b)
Since there are doors and windows, area of the walls
= 2 * 12 (15 + 25) - (6 * 3) - 3(4 * 3)
= 906 sq.ft.
Total cost = 906 * 5 = Rs. 4530

Question: Machine A produces 100 parts twice as fast as Machine B does. Machine B produces 100 parts in 40 minutes. If each machine produces parts at a constant rate, how many parts does Machine A produce in 10 minutes?
A.20
B.50
C.60
D.40
Answer: B.50
Explanation: Machine B produces 100 part in 40 minutes. Machine A produces 100 parts twice as fast as B, so Machine A produces 100 parts in 40/2=20 minutes.
Now, Machine A produces 100 parts in 20 minutes which is 100/20 = 5 parts/minute.
5 parts X a total of 10 minutes = 50

Question: What is the probability that when a hand of 6 cards is drawn from a well shuffled deck of 52 cards, It contains 2 Queen?
A.1/23445
B.113/22434
C.29187/1017926
D.1017926/29187
Answer: C.29187/1017926
Explanation: nCr = n!/(n-r)!r!
Total number of possible hands = 52C6
52C6 = (52!)/((52-6)! × 6!)
52C6 = 61075560.
Number of hands with 2 Queen and 4 non-Queen cards = 4C2 × 48C4
4C2 = (4!)/(2! × 2!) = 6.
48C4 = (48!)/(44! × 4!) = 3 × 47 × 46 × 45 = 291870
(other 2 cards must be chosen from the rest 48 cards)
P (2 Queen) = (4C2 × 48C4)/52C6 = 29187/1017926

Question: A train running at 25 km/hr takes 18 seconds to pass a platform. Next, it takes 12 seconds to pass a man standing still. Find the length of the train and that of the platform.
A.83.3m41.7m
B.100m50m
C.50.8m45.7m
D.100/3 m200/3
Answer: A.83.3m41.7m
Explanation: A train running at 25 km/hr takes 18 seconds to pass a platform. Next, it takes 12 seconds to pass a man walking at 5 km/hr in the same direction. Find the length of the train and that of the platform.
Distance = Speed*time
It's probably best to convert to meters so we can find the length of the platform.
Distance = 25000 meters/h * 18 seconds*(1/60*60)
Distance =(25000*18 / [3600] ) = 125m
I'm not sure how we take the length of the train into account (if we do at all) to solve this problem. For example, If we were measuring by the time the very front of the train passed one end of the platform to the time the very front of the train passed the other end, the result would be different than if we counted when the very front of the train passed one end of the platform to the time the back side of the train passed the end.
As for the problem involving the man, the man is standing still while the train is moving forward at a speed of 25km/h. Therefore, the train is moving past the man at a total speed of 25km/h.
distance = speed * time
distance = 25km/h * 12 seconds
distance (length of train) = 83.3 m
We know the length of the train is roughly 83.3m and the distance covered passing the platform was 125m. However, The platform isn't 125m long - it is 125m minus the length of the train long (or so I think) which is 125-83.3 or roughly 41.7m. Both of these answers are in A so I think that is the right answer. I am still having a bit of trouble conceptualizing why we have to subtract out the length of the train, however.

Question: A certain high school has 500 students. Of these students, 30 are taking music, 20 are taking art, and 10 are taking both music and art. How many students are taking neither music nor art?
A.430
B.440
C.450
D.460
Answer: D.460
Explanation: We're given a series of facts to work with:
1) A certain high school has 500 students.
2) Of these students:
X are taking music,
Y are taking art, and
Z are taking BOTH music and art.
We're asked how many students are taking NEITHER music nor art?
Let's TEST
X = 30
Y = 20
Z = 10
So, we have 30 students taking music, 20 taking art and 10 taking BOTH music and art.
20 student taking JUST music
10 student taking JUST art
10 student taking BOTH music and art
Total = 40 students
We're asked for the total number of students who are taking NEITHER Course. That is 500 - 40 = 460.

Question: A fort had provision of food for 150 men for 45 days. After 10 days, 25 men left the fort. Find out the number of days for which the remaining food will last
A.44
B.42
C.40
D.38
Answer: B.42
Explanation: Explanation :
Given that fort had provision of food for 150 men for 45 days
Hence, after 10 days, the remaining food is sufficient for 150 men for 35 days
Remaining men after 10 days = 150 - 25 = 125
Assume that after 10 days,the remaining food is sufficient for 125 men for x days
More men, Less days (Indirect Proportion)
⇒Men150:125}::x:35
⇒ 150 × 35 = 125x
⇒ 6 × 35 = 5x
⇒ x =6 × 7 = 42
⇒The remaining food is sufficient for 125 men for 42 days. Answer : Option B
