Question: If r and s are positive integers and r-s=6, which of the following has the greatest value Q?
A.2r
B.2s
C.r +s
D.2r-s
Answer: A.2r
Explanation: The simplest way to do this is to assume values.
We are told that r and s are positive integers Q.
Also, r-s = 6 => r = 6+s
Hence r is 6 more than s.
Let s be 10. Hence r = 16.
Option A: 2r = 2*16 = 32
Option B: 2s = 2 * 10 = 20
Option C: r + s = 16 + 10 = 26
Option D: 2r - s = 2(16) - 10 = 32 - 10 = 22
Option E: 2s - r = 2(10) - 16 = 20 - 16 = 4
Hence option A is the greatest.

Question: 8^100 is divisible by 17. Find the remainder?
A.10
B.12
C.16
D.18
Answer: C.16
Explanation: This is an extremely difficult problem to solve with out Fermat's little theorem. By applying Fermat's little theorem , We know that 816 when divided by 17, the remainder is 1.
So divide 100 by 16 and find the remainder. Remainder = 4
Therefore, 100 = (16 × 6) + 4
Now this problem can be written as 810017 = 816×6+417 = (816)6×8417
Now this problem simply boils down to (1)6×8417 = 8417
84 = 82×82, we need to find the remainder when 64 × 64 is divisible by 17. Or 13 × 13 = 169. When 169 is divided by 17, remainder is 16.

Question: If a survey shows that 26 citizens out of a sample of 200 support a particular Senate bill, what percent of the sample does not support the bill?
A. 56%
B. 64%
C. 72%
D. 87%
Answer: D. 87%
Explanation: 26 out of 200 supports the bill and we are asked to find the percent who the does not support the bill.
26 out of 200 supports the bill = 13 out of 100 supports the bill ( taking in % terms )
14 out of 100 supports the bill = 87 (100-13) doesn't support the bill
So, answer is (D) 87%
Question: Length of a rectangular plot is 20 mtr more than its breadth. If the cost of fencin gthe plot at 26.50 per meter is Rs. 5300, what is the length of the plot in mtr?
A.45 m
B.60 m
C.50 m
D.67 m
Answer: B.60 m
Explanation: Let breadth = x metres.
Then, length = (x + 20) metres.
Perimeter = 5300 m = 200 m.
26.50
2[(x + 20) + x] = 200
2x + 20 = 100
2x = 80
x = 40.
Hence, length = x + 20 = 60 m

Question: The rhombus (AFCE) is inscribed in rectangle (ABCD). The length of BF = DE.
If the rectangle has a width of 20 yards and a length of 25 yards, what would be the total length (the perimeter) of a fence along the sides defined by AFCE?
A.80 yards
B.82 yards
C.84 yards
D.85 yards
Answer: B.82 yards
Explanation: The definition of a rhombus states that every side is of equal length. This definition is the key to solving this question.
1) We state that the hypotenuse of either side triangle is x. For this solution, I will be working with the left triangle.
2) We state that the bottom and top sides of the rhombus are also x, due to the definition of a rhombus.
3) We will define the bottom of the left triangle as y. That is, for the rectangle bottom itself, we can define it as 25 = y + x, where x is a side for the rhombus and y is the bottom part of the left triangle.
4) From (1), we know that x = 202+y2−−−−−−−√202+y2.
5) From (3), we know x = 25 - y.
6) From (4) and (5), we have the equation 202+y2−−−−−−−√=25−y202+y2=25−y
7) Solving for y, we get 4.5.
8) 25 - 4.5 = 20.5 = x
9) Since all sides of the rhombus are the same, 20.5 * 4 = 41 * 2 = 82.
The answer is B, 82
Question: There are 5 boxes in a cargo. The weight of the 1st box is 200 KG, the weight of the 2nd box is 20% higher than the third box, whose weight is 25% higher than the 1st box weight. The 4th box which weighs 350 KG is 30% lighter than the 5th box. Find the difference in average weight of the 4 heaviest boxes and the four lightest boxes.
A.22
B.75
C.25
D.70
Answer: B.75
Explanation: weight of 1st box=200
weight of 3rd box=(125/100)*200=250
weight of 2nd box=(120/100)*250=300
weight of 4th box =350
weight of 5th box=(10/7)*350=500
average of 4 highest weighted boxes=(500+350+300+250)/4=350
average of 4 lightest boxes=(350+300+250+200)/4=275
therefore difference=350-275=75

Question: A wooden cube whose edge length is 7 inches is composed of smaller cubes with edge lengths of one inch. The outside surface of the large cube is painted red and then it is split up into its smaller cubes. If one cube is randomly selected from the small cubes, what is the probability that the cube will have at least one red face?
A.59.8%
B.63.6%
C.67.2%
D.70.5%
Answer: B.63.6%
Explanation: There are a total of 7*7*7 = 343 cubes.
All the exterior cubes will have at least one face painted red.
The interior is formed by 5*5*5 = 125 cubes.
The number of cubes with at least one side painted red is 343 - 125 = 218 cubes
The probability that a cube has at least one side painted red is 218/343 which is about 63.6%
The answer is B.
Question: A school has received 80% of the amount it needs for a new building by receiving a donation of $600 each from people already solicited. People already solicited represent 40% of the people from whom the school will solicit donations. How much average contribution is requited from the remaining targeted people to complete the fund raising exercise?
A.$200
B.100
C.$105
D.$250
Answer: B.100
Explanation: Let us suppose there are 100 people. 40% of them donated $ 24000 ( 600 * 40 )
$24000 is 80% of total amount.
So total amount = 24000 * 100/80
Remaining amount is 20% of total amount.
20% of total amount = 24000 * (100/80) * (20/100) =6000
This amount has to be divided by 60 ( remaining people are 60 )
So per head amount is 6000/ 60 = $100

Question: A certain list of 300 test scores has an arithmetic mean of 75 and a standard deviation of d, where d is positive. Which of the following two test scores, when added to the list, must result in a list of 303 test scores with a standard deviation less than d?
A. 75 and 80
B. 75 and 75
C. 70 and 75
D. 75 and 70
Answer: B. 75 and 75
Explanation: Deviation means spreading of the numbers from one median point value..
as the set is already established and we need to add only two numbers, this means we can only add numbers which are closer to the median to reduce the deviation.
so 75 and 75 are the most close numbers and they will increase the number of elements in the set without changing the median value.

A.5 days
B.10 days
C.14 days
D.22 days
Answer: A.5 days
Explanation: Explanation :
Work done by P in 1 day = 1/10
Work done by Q in 1 day = 1/6
Work done by P in 2 days = 2 Ã— (1/10) = 1/5
Remaining work = 1 â€“ 1/5 = 4/5
Work done by P and Q in 1 day = 1/10 + 1/6 = 4/15
Number of days P and Q take to complete the remaining work = (4/5) / (4/15) = 3
Total days = 2 + 3 = 5

Question: The integers 1, 2, … , 40 are written on a blackboard. The following operation is then repeated 39
times: In each repetition, any two numbers, say a and b, currently on the blackboard are erased and a new
number a + b – 1 is written. What will be the number left on the board at the end?
A.23
B.122
C.781
D.377
Answer: C.781
Explanation: Initial sum of the number 1 to 40 = n(n+1)2=40×412=840n(n+1)2=40×412=840
After erasing two numbers a and b, and replacing with (a + b − 1), the new sum of the terms of the
sequence = 820 − 1
Similarly, after every operation, the sum of the terms of the sequence reduces by 1.
∴ The last number left (i.e. final sum) = 820 − 39 = 781

Question: What is the number of integers from 1 to 1000 (inclusive) that are divisible by neither 11 nor by 30?
A.884
B.890
C.892
D.910
Answer: A.884
Explanation: Normally, I would use the method used by Bunuel. It's the most accurate. But if you are looking for a speedy solution, you can use another method which will sometimes give you an estimate. Looking at the options (most of them are spread out), I wont mind trying it. (Mind you, the method is accurate here since the numbers start from 1.)
In 1000 consecutive numbers, number of multiples of 11 = 1000/11 = 90 (Ignore decimals)
In 1000 consecutive numbers, number of multiples of 35 = 1000/35 = 28
Number of multiples of 11*35 i.e. 385 = 1000/385 = 2
Number of integers from 1 to 1000 that are divisible by neither 11 nor by 35 = 1000 - (90 + 28 - 2) {Using the concept of sets here) = 884
Think: Why did I say the method is approximate in some cases?
Think what happens if the given range is 11 to 1010 both inclusive (again 1000 numbers)
What is the number of multiples in this case?
A
Question: What is the least number of cut pieces of equal length that can be cut out of two lengths 10 meters 857 millimeters and 15 meters 87 millimeters.
A.184
B.266
C.255
D.887
Answer: A.184
Explanation: Here, you need to find the HCF. Because, to get least number of equal cut pieces you should cut as big as possible. So, HCF of 10857 and 15087 = 141. (This is the size of each cut piece). Then the number of cut pieces = (10857 + 15087) ÷ 141 = 184.

Question: Mr. Smith calculated the average of 10three digit numbers. But due to a mistake he reversed the digits of a number and thus his average increased by 19.8. The difference between the unit digit and hundreds digit of that number is :
A.a) 4
B.b) 3
C.c) 2
D.d) 1
Answer: C.c) 2
Explanation: Since the average increased by 19.8 and there were a total of 10 numbers, it means the incorrect number was 198 greater than the correct number.
Say, the correct number was abc (where a, b and c are the digits of the 3 digit number)
Then the incorrect number was cba.
100c + 10b + a - (100a + 10b + c) = 198
99c - 99a = 99(c - a) = 198
198 = 99*2 = 99(c - a)
So c - a = 2

Question: The parameter of a square is equal to the perimeter of a rectangle of length 16 cm and breadth 14 cm. Find the circumference of a semicircle whose diameter is equal to the side of the square. (Round off your answer to two decimal places)?
A.23.58
B.23.56
C.23.54
D.23.57
Answer: D.23.57
Explanation: Let the side of the square be a cm.
Parameter of the rectangle = 2(16 + 14) = 60 cm Parameter of the square = 60 cm
i.e. 4a = 60
A = 15
Diameter of the semicircle = 15 cm
Circimference of the semicircle
= 1/2(∏)(15)
= 1/2(22/7)(15) = 330/14 = 23.57 cm to two decimal places

Question: A farmer has an apple orchard consisting of Fuji and Gala apple trees. Due to high winds this year 10% of his trees cross pollinated. The number of his trees that are pure Fuji plus the cross-pollinated ones totals 204, while 3/4 of all his trees are pure Fuji. How many of his trees are pure Gala?
A.22
B.36
C.55
D.77
Answer: B.36
Explanation: Let f = pure fuji , g = pure gala and c - cross pollinated.
c = 10% of x where x is total trees.
c = .1x
also 3x/4 = f and c+f = 204 => .1x + 3/4x = 204 => x = 240
240 - 204 = pure gala = 36.
Answer B
Question: If MAPLE is coded as VOKZN then how will CAMEL be coded?
A.OVNZF
B.OUNZX
C.OVNZX
D.XZNVO
Answer: C.OVNZX
Explanation: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Z Y X W V U T S R Q P O N M L K J I H G F E D C B A
So each alphabet is replaced by the above rule and also whole word is reversed i.e MAPLE - after just replacing each alphabet (by above rule) we get NZKOV,then we reverse this word again and we get VOKZN.
so this way CAMEL becomes OVNZX
