Question: A train passes a station platform in 36 sec and a man standing on the platform in 20 sec. If the speed of the train is 72 km/hr. What is the length of the platform?
Options:
A)229
B)240
C)288
D)277
E)320
Rationale: Speed = 72 * 5/18 = 20 m/sec.
Length of the train = 20 * 20 = 400 m.
Let the length of the platform be x m . Then,
(x + 400)/36 = 20 => x = 320 m.
Answer: E
Answer: E

B)87
C)40
D)99
E)77
Rationale: 3W = 2M
20M ------ 21 * 8 hours
21 W ------ x * 6 hours
14 M ------ x * 6
20 * 21 * 8 = 14 * x * 6
x = 40

Answer: C
Question: A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is?
Options:
A)27
B)50
C)27
D)29
E)12
Rationale: Speed of the train relative to man = (125/10) m/sec = (25/2) m/sec. [(25/2) * (18/5)] km/hr = 45 km/hr. Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr. x - 5 = 45 ==> x = 50 km/hr.

Question: An analysis of the monthly incentives received by 5 salesmen : The mean and median of the incentives is $7000. The only mode among the observations is $12,000. Incentives paid to each salesman were in full thousands. What is the difference V between the highest and the lowest incentive received by the 5 salesmen in the month?
Options:
A)$4000
B)$5000
C)$9000
D)$11,000
E)$13,000
Rationale: Break down the question in to steps:
Step #1: incentives received by 5 salesmen -->abcde
Step #2: mean and median of the incentives is $7000: via number properties --> total incentives = 7,000 * 5 = 35, 000ab7,000de
Step #3: only mode among the observations is $12,000: mode is the value that appears most often in a set of data. Therefore 12,000 must occur more then once and since 12,000 is larger than the mean (7,000) the most it can occur is twice in our list. If we place the numbers in ascending order we haveab7,00012,00012,000
Step #4: What is the difference between the highest and the lowest incentive:
- The total paid has to equal mean * # of numbers = 7,000 * 5 = 35 000.
- The three values we have so far (12,000 12,000 and 7, 000) equal 31,000.
- Therefore the first two numbers( ab) must equal 4, 000
- There is only one mode which is 12,000, therefore 4,000 must be equal to a set of two numbers that are not the and a < b
if a = 1,000 b = 3,000 --> difference V between the highest and the lowest incentive = 12,000 - 1,000 =11, 000
no other options for a or b to fit the criteria

Question: A farm is made up of brown and white goats. the number of male brown goats is 35% less than the total number of brown goats. The total number of female goats is 20 times more than the number of female brown goats. If the total population of male goats is half the population of the female goats, what percentage of male goats are brown?
Options:
A)30.1
B)20.5
C)15.2
D)10.2
E)28.6
Rationale: Since we are dealing in percentage let us pick 100 as the number of brown male goats.
That means that the total number of brown goats is= 135 (number of male brown goats is 35% less than the total number of brown goats),
therefore the number of brown female goats is 35.
The total number of female goats is 15x the number of brown female goats= 35*20=700 female goats.
Male goats total population is half the population of the female goats = 700/2=350
Therefore percentage of male horses goats that are brown= 100/350*100=28.6
Correct option is E
Answer: E
Question: When a person aged 39 is added to a group of n people, the average age increases by 2. When a person aged 15 is added instead, the average age decreases by 1. What is the value of T?
Options:
A) 7
B) 8
C) 9
D) 10
E) 11
Rationale: A simple and elegant solution.
As addition of 39, shifts mean by 2, and addition of 15, shifts mean by 1 to the other side, we have the mean lying between 3915, and in a ratio of 2:1
39-15 = 24
24 divide by 3 is 8.
Meaning mean of the n terms is 15+8 = 39-16 = 23
Now, from first statement, When a person aged 39 is added to a group of n people, the average age increases by 2.
T*23 +39 = 25*(T+1)
T = 7

Question: In how many ways can 22 books on English and 20 books on Hindi be placed in a row on a shelf so that two books on Hindi may not be together?
Options:
A)4586
B)5896
C)2415
D)1771
E)1881
Rationale: In order that two books on Hindi are never together, we must place all these books as under:
H E H E H E H….. H E H
Where H denotes the position of Hindi book and E that of English book.
Since there are 22 books on English, the number of places marked E are 23.
Now, 20 places out of 23 can be chosen in 23C20 = 23C3 = 23*22*21
3*2*1
= 1771 ways.
Hence the number of ways = 1771 ways

Question: A math teacher has 24 cards, each of which is in the shape of a geometric figure. Half of the cards are rectangles, and a third of the cards are rhombuses. If 8 cards are squares, what is the maximum possible number of cards that re circles.
Options:
A)7
B)10
C)11
D)12
E)13
Rationale: a square is a special kind of rhombus (sides are perpendicular)
a square is a special kind of rectangles (sides with same length)
Among the 24 cards with have:
15 rectangles
10 rhombus
8 squares
Among the 15 rectangles, there could be 8 special ones (with sides of same length) that are squares. That lets at least 7 rectangles that are not square.
Among the 10 rectangles, there could be 8 special ones (with sides perpendicular) that are squares. That lets at least 2 rhombus that are not square.
We have 8 squares.
So the minimum different cards that represent a square, a rhombus or a rectangle is 2 + 7 + 8 = 17
Which means that the maximum number of circles that you could have is 24 - 17 = 7

Question: The price of 10 chairs is equal to that of 4 tables. The price of 15 chairs and 2 tables together is Rs. 4000. The total price of 12 chairs and 3 tables is:
Options:
A)Rs. 3900
B)Rs. 3990
C)Rs. 4000
D)Rs. 4100
E)Rs. 4200
Rationale: Let the cost of a chair and that of a table be Rs. x and Rs. y respectively.
Then, 10x = 4y or y = 5 x.
2
15x + 2y = 4000
15x + 2 x 5 x = 4000
2
20x = 4000
x = 200.
So, y = 5 x 200 = 500.
2
Hence, the cost of 12 chairs and 3 tables = 12x + 3y
= Rs. (2400 + 1500)
= Rs. 3900.

Question: A and B start a business, with A investing the total capital of Rs.50000, on the condition that B pays A interest @ 10% per annum on his half of the capital. A is a working partner and receives Rs.1500 per month from the total profit and any profit remaining is equally shared by both of them. At the end of the year, it was found that the income of A is twice that of B. Find the total profit for the year?
Options:
A)59028
B)27777
C)29999
D)59000
E)27772
Rationale: Interest received by A from B = 10% of half of Rs.50000 = 10% * 25000 = 2500.
Amount received by A per annum for being a working partner = 1500 * 12 = Rs.18000.
Let 'P' be the part of the remaining profit that A receives as his share. Total income of A = (2500 + 18000 + P)
Total income of B = only his share from the remaining profit = 'P', as A and B share the remaining profit equally.
Income of A = Twice the income of B
(2500 + 18000 + P) = 2(P)
P = 20500
Total profit = 2P + 18000
= 2*20500 + 18000 = 59000.Answer:D

Question: Each customer of a networking company subscribes to one of two plans: Plan A or Plan B. Plan A costs $100 per month and Plan B costs $200 per month per customer. If the company’s average revenue per customer per month is $150, then what percent of the company's revenue comes from customers with Plan A?
Options:
A)25%
B)30%
C)37.5%
D)56.25%
E)75%
Rationale: We can show this algebraically:
If there are A customers with plan A, and B customers with plan B, then the total revenue is $100A + $200B.
Since the average customer pays $75, we know that
$150 = ($100A + $200B) / (A + B)
$150(A + B) = ($100A + $200B)
$150A + $150B = $100A + $200B
$50A = $50B
A = B.
Since there are Equal times as many $100 clients as $200 clients, for every $200 received from Plan B customers, $100 is received from Plan A customers, and the percent of revenue from customers with Plan A is:
$100/($100 + $200) = $100/$300 = 30%.

Question: A teacher gave the same test to three history classes: K, B, and C. The average (arithmetic mean) scores for the three classes were 65, 80, and 77, respectively. The ratio of the numbers of students in each class who took the test was 4 to 6 to 5, respectively. What was the average score for the three classes combined?
Options:
A)74
B)75
C)76
D)77
E)78
Rationale: Ans : B (75)
lets say class K indeed has 4 children, B has 6 children and C has 5 children.
now, if the average of class K is 65, hence total marks awarded in the class = 65*4=260
Similarly,
class B = 80*6 = 480
class C = 77*5 = 385
total marks provided = K+B+C = 260+480+385 = 1125
avg. marks = 1125 / 15 (total no. of students) = 75=B

Options:
A)4 years
B)6 years
C)8 years

150×6×n=800×9/2×2
150×6×n=800×9
3×6×n=16×9
6×n=16×3
2×n=16

Options:
A)22
B)12
C)67
D)20
E)81
Rationale: Relative speed = (42 + 30) * 5/18 = 4 * 5 = 20 mps.
Distance covered in passing each other = 120 + 280 = 400 m.
The time required = d/s = 400/20 = 20 sec.

Question: When sold at a 40% discount, a sweater nets the merchant a 30% profit on the wholesale cost at which he initially purchased the item. By what % is the sweater marked up from wholesale at its normal retail price?
Options:
A)20%
B)40%
C)50%
D)53.85%
E)100%
Rationale: we should be careful about what are we measuring % on/what is the base..
let the Marked up price =100..
Selling price= 100-40%of 100=60..
profit= 30%..
therefore the wholesale purchase cost= x.... 1.3x=60
or x=46.15...
marked price was 100 so ...
so answer is 53.85%..
