The average height of 35 boys in a class was calculated as 180cm. It has later found that the height of one of the boys in the class was wrongly written as 166 cm whereas his actual height was 106 cm. Find the actual average height of the boys in the class (Round off your answer to two decimal places).? Choose the correct choice from the following answers:
A) 178.27 cm  B) 178.29 cm  C) 978.29 cm  D) 178.89 cm  E) 176.29 cm

Solution: Calculated average height of 35 boys = 180 cm.   Wrong total height of 35 boys = 180 * 35 cm. This was as a result of an actual height of 106 cm being wrongly written as 166 cm. Correct total height of 35 boys = 180 * 35 cm - 166 cm + 106 cm   = 180 * 35 cm - 166 cm + 106 cm/35 = 180 cm - 60 /35 cm   = 180 cm - 1.71 cm = 178.29 cm.   Answer: 178.29 cm

An error 3% in excess is made while measuring the side of a square. The percentage of error in the calculated area of the square is: Choose the correct choice from the following options.
A) 6.05
B) 6.09
C) 6.03
D) 6.02
E) 6.01

Solution: Explanation:   100 cm is read as 103 cm.   A1 =(100 × 100)cm2 = 10000   and A2= (103 × 103)cm2= 10609   (A2 - A1) = 10609-10000= 
10609-10000 = 609
609=> 609/10000*100= 
609/10000*100 = 609/100 = around 6.09
6.09   Answer : 6.09

A) A)0.8321	B) B)0.7	C) C)0.8571	D) D)0.926	E) E)0.896

Solution: Out of 100 matches:   Matt is plays in 90 and not plays in 10.   Out of 90 matches Matt plays in, team wins   0.70*90= 
  0.70*90 = 63
63.   Out of 10 matches Matt does not play in, team wins   0.5*10= 
  0.5*10 = 5
5.   So, out of 100 matches 63 + 5= 
63 + 5 = 68
68 are won.   It is known that the team has won the last match. Out of 68 matches won, Matt is in 63: 63/68= 0.926...   Answer: 0.926.

In certain year in Country C, x sets of twins and y sets of triplets were born. If there were z total babies born in Country C in this year, and x and y were both greater than 0, which of the following represents the fraction W of all babies born who were NOT part of a set of twins or triplets?
Pick one:
A) z - 2x - 3y
B) (2x+3y)/z
C) (x+y)/z
D) 1 - (2x+3y)/z
E) 1 - (x+y)/z

Solution: X set of twins implies 2x babies of twin category.   Y set of triplets means 3y babies of triplet category.   Let K be the babies other than twin or triplet category.   Total babies = z = 2x+3y+k.   or K=Z-(2x+3y)   => Fraction of babies other than twin or triplet categories = K/Z = Z-(2x+3y)/Z.   W= 1- (2x+3y)/Z. Hence answer is 1 - (2x+3y)/z.

At a meeting, 7 people are to be seated around a circular table. Two seating arrangements are considered different only when the positions of the people are different relative to each other. What is the total number of different possible seating arrangements for the group?
Select the correct option:
A) 12	B) 72	C) 120	D) 144	E) 720

Solution: The number of arrangements of n distinct objects in a row is given by n!   The number of arrangements of n distinct objects in a circle is given by (n−1)!   "The difference between placement in a row and that in a circle is following: if we shift all object by one position, we will get different arrangement in a row but the same relative arrangement in a circle. So, for the number of circular arrangements of n objects we have:   R=n!-n=(n−1)!   (n−1)!=(7−1)!=720   Answer: 720

Find the number of factors E of 180 that are in the form (4*k + 2), where k is a non-negative integer?	Pick one
A) 1  B) 2  C) 3  D) 4  E) E=6

Solution: As for the question, the most straightforward way is to list out the factors (this is fine for this question as 180 is a relatively small number). Number of factors of 180 E(=2^2*3^2*5) = 18. So listing the factors gives us:   1, 180   2, 90   3, 60   4, 45   5, 36   6, 30   9, 20   10, 18   12, 15   As the question asks us about the factors of the form 4k+2 ---> eliminate all ODD factors. You are now left with   2,4,6,10,12,18,20,30,36,60,90,180   For the form 4k+2, the first few values are 2, 6, 10, 14, 18, 22, 26, 30 ... already giving you 5 factors (=2,6,10,18,30). You can stop here and mark 6 (6th one = 90) as the correct answer as 5 is not given.   For checking any particular factor whether they conform to the form 4k+2---> do the following   4k+2 = 36 ---> 4k = 34 --> this will NOT give you an integer value for k ---> reject. Proceed with others until you find all the values asked.   E=6 is thus the correct answer.

The area of the square formed on the diagonal of a rectangle as its side is 108 1/3 % more than the area of the rectangle. If the perimeter of the rectangle is 28 units, find the difference between the sides of the rectangle?  Choose the most appropriate option:
A) 1
B) 3
C) 4
D) 2
E) 5

Solution: Let the sides of the rectangle be l and b respectively.   From the given data,   (l2 + b2) = (1 + 108 1/3 %)lb   => l2 + b2 = (1 + 325/3 * 1/100)lb   = (1 + 13/12)lb   = 25/12 lb   => (l2 + b2)/lb = 25/12   12(l2 + b2) = 25lb   Adding 24lb on both sides   12l2 + 12b2 + 24lb = 49lb   12(l2 + b2 + 2lb) = 49lb   but 2(l + b) = 28 => l + b = 14   12(l + b)2 = 49lb   => 12(14)2 = 49lb   => lb = 48   Since l + b = 14, l = 8 and b = 6   l - b = 8 - 6= 
8 - 6 = 2

In one day, Juan sends Keith three times as many messages as he sends Laurence, and Laurence sends Missy 5 times as many messages as he receives from Juan. If Missy received 25 messages from Laurence, how many messages does Keith receive from Juan?
Choose the correct choice from the following options:
A) 3
B) 12
C) 15
D) 18
E) 56

Solution: Juan --> Laurence = x messages;   Juan --> Keith = 3x messages (Juan sends Keith three times as many messages as he sends Laurence);   Laurence --> Missy = 5x =25 (Laurence sends Missy 5 times as many messages as he receives from Juan).   5x =25 --> x = 5 --> 3x = 15.   Answer: 15.

In country Z, 10% of the people do not have a university diploma but have the job of their choice, and 25% of the people who do not have the job of their choice have a university diploma. If 20% of the people have the job of their choice, what percent of the people have a university diploma? Choose one.
A) 30%
B) 45%
C) 55%
D) 65%
E) 75%

Solution: Setting up a matrix is how I solve this one.   Diploma No Diploma Totals   Job of Choice w/Diploma   Job of Choice w/o Diploma = 10%   Job of Choice Total = 20%   Not Job of Choice with Diploma =.25X   Not Job of Choice w/o Diploma= .75X   Total Not Job of Choice = X   Total with Diploma   Total without Diploma   Total citizen = 100   If 20% of people have their job of choice, then 80% of people do NOT have their job of choice. 25% of 80% = 20%. We can also see that 10% of the people have their job of choice and a diploma (20%-10%=10%). 10% + 20% = 30%. Therefore 30% of the people in Country Z have a diploma.   30%ns 30%
Answer: A
The average height of 6 people is 67 inches. When Robert's height is included, the average increases by 2 inches. How tall is Robert in inches?
Choose the correct choice from the following options:
A) 81	B) 72	C) 69	D) 84	E) 67

Solution: Total height of 6 people = 6*67= 
6*67 = 402
402   Total height of 7 people= 7*69= 
7*69 = 483
483   Robert's height= 483-402= 
483-402 = 81
81 inches   81nswer is 81
Answer: A
A card game called “high-low” divides a deck of 52 playing cards into 2 types, “high” cards and “low” cards. There are an equal number of “high” cards and “low” cards in the deck and “high” cards are worth 2 points, while “low” cards are worth 1 point. If you draw cards one at a time, how many ways can you draw “high” and “low” cards to earn 7 points if you must draw exactly 5 “low” cards?	Answers:
A) 6 B) 2 C) 3 D) 4 E) 5

Solution: Great question Ravih. This is a permutations problem (order matters) with repeating elements. Given thatlowcards are worth 1 pt andhigh cards2 pts, and you must draw 3 low cards, we know that you must also draw 1 high card. The formula for permutations problems with repeating elements isN!/A!B!...where N represents the number of elements in the group and A, B, etc. represent the number of times that repeating elements are repeated. Here there are 4 elements and thelowcard is repeated 3 times. 6s a result, the formula is:   6!/5! which represents (6*5*4*3*2*1)/(5*4*3*2*1) which simplifies to just 6, giving you answer 6.
