### Samples

Number series:

In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much

1. Look at this series: 2, 1, ($$\frac{1}{2}$$), ($$\frac{1}{4}$$), … What number should come next?

A. ($$\frac{1}{3}$$)
B. ($$\frac{1}{8}$$)
C. ($$\frac{2}{8}$$)
D. ($$\frac{1}{16}$$)

Explanation:
This is a simple division series; each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.
$$\frac{4}{2}$$ = 2
$$\frac{2}{2}$$ = 1
$$\frac{1}{2}$$ = $$\frac{1}{2}$$
$$\frac {(\frac {1}{2})}{2}$$= $$\frac{1}{4}$$
$$\frac {(\frac {1}{4})}{2}$$ =$$\frac{1}{8}$$and so on.

2. Look at this series: 7, 10, 8, 11, 9, 12, … What number should come next?

B. 10
C. 12

A. 11 5
B. 10 7
C. 11 8

A. Sunday
B. Saturday
C. Friday
D. Wednesday

Explanation:
On 31st December, 2005 it was Saturday.
Number of odd days from the year 2006 to the year 2009 = (1 + 1 + 2 + 1) = 5 days.
On 31st December 2009, it was Thursday.
Thus, on 1st Jan 2010, it is Friday.

2. What was the day of the week on $$28^{th}$$ May 2006?

A. Thursday
B. Friday
C. Saturday
D. Sunday

Explanation:
$$28^{th}$$ May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)
Odd days in 1600 years = 0
Odd days in 400 years = 0
5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) 6 odd days
Jan. Feb. March April May
(31 + 28 + 31 + 30 + 28 ) = 148 days
148 days = (21 weeks + 1 day) 1 odd day.
Total number of odd days = (0 + 0 + 6 + 1) = 7 0 odd day.
Given the day is Sunday.

3. What was the day of the week on $$17^{th}$$June 1998?

A. Monday
B. Tuesday
C. Wednesday
D. Thursday

Explanation:
$$17^{th}$$June, 1998 = (1997 years + Period from 1.1.1998 to 17.6.1998)
Odd days in 1600 years = 0
Odd days in 300 years = (5 x 3) 1
97 years has 24 leap years + 73 ordinary years.
Number of odd days in 97 years ( 24 x 2 + 73) = 121 = 2 odd days.
Jan. Feb. March April May June
(31 + 28 + 31 + 30 + 31 + 17) = 168 days
168 days = 24 weeks = 0 odd day.
Total number of odd days = (0 + 1 + 2 + 0) = 3.
Given the day is Wednesday.

4. What will be the day of the week $$15^{th}$$ August 2010?

A. Sunday
B. Monday
C. Tuesday
D. Friday

Explanation:
$$15^{th}$$ August, 2010 = (2009 years + Period 1.1.2010 to 15.8.2010)
Odd days in 1600 years = 0
Odd days in 400 years = 0
9 years = (2 leap years + 7 ordinary years) = (2 x 2 + 7 x 1) = 11 odd days 4 odd days.
Jan. Feb. March April May June July Aug.
(31 + 28 + 31 + 30 + 31 + 30 + 31 + 15) = 227 days
227 days = (32 weeks + 3 days) 3 odd days.
Total number of odd days = (0 + 0 + 4 + 3) = 7 0 odd days.
Given the day is Sunday.

5. Today is Monday. After 61 days, it will be:

A. Wednesday
B. Saturday

Problem Solving:

1. If one-third of one-fourth of a number is 15, then three-tenths of that number is:

A. 35
B. 36
C. 45
D. 54

Explanation:
Let the number be x.
Then,$$\frac{1}{3}$$ of $$\frac{1}{3}$$ of x= 15
x = 15 x 3 x 4 = 180.
So, required number = ($$\frac{3}{10}$$x 180)= 54.

2. Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is:

A. 9
B. 11
C. 13
D. 15

Explanation:

Let the three integers be x, x + 2 and x + 4.
Then, 3x = 2(x + 4) + 3
x = 11.
Third integer = x + 4 = 15.

3. The difference between a two-digit number and the number obtained by interchanging the positions of its digits is 36. What is the difference between the two digits of that number?

A. 3
B. 4
C. 9
D. Cannot be determined
E. None of these

Explanation:
Let the ten’s digit be x and unit’s digit be y.
Then, (10x + y) – (10y + x) = 36
9(x – y) = 36
x – y = 4.

4. The difference between a two-digit number and the number obtained by interchanging the digits is 36. What is the difference between the sum and the difference of the digits of the number if the ratio between the digits of the number is 1: 2?

A. 4
B. 8
C. 16
D. None of these

Explanation:
Since the number is greater than the number obtained on reversing the digits, so the ten’s digit is greater than the unit’s digit.
Let ten’s and unit’s digits are 2x and x respectively.
Then, (10 x 2x + x) – (10x + 2x) = 36
9x = 36
x = 4.
Required difference = (2x + x) – (2x – x) = 2x = 8.

5. A two-digit number is such that the product of the digits is 8. When 18 is added to the number, then the digits are reversed. The number is:

A. 18
B. 24
C. 42
D. 81

Explanation:

Let the ten’s and unit digit be x and $$\frac{8}{x}$$respectively.
Then,(10x+$$\frac{8}{x}$$) + 18 = 10*$$\frac{8}{x}$$ + x
10$$x^{2}$$ + 8 + 18x = 80 + x2
9×2 + 18x – 72 = 0
x2 + 2x – 8 = 0
(x + 4)(x – 2) = 0
x = 2.

Decision Making:

1. Eileen is planning a special birthday dinner for her husband’s 35th birthday. She wants the evening to be memorable, but her husband is a simple man who would rather be in jeans at a baseball game than in a suit at a fancy restaurant. Which restaurant below should Eileen choose?

A. Alfredo’s offers fine Italian cuisine and elegant Tuscan decor. Patrons will feel as though they’ve spent the evening in a luxurious Italian villa.
B. Pancho’s Mexican Buffet is an all-you-can-eat family style smorgasbord with the best tacos in town.

D. Marty’s serves delicious, hearty meals in a charming setting reminiscent of a baseball clubhouse in honor of the owner, Marty Lester, a former major league baseball all-star.

Explanation:
Since Eileen’s husband does not enjoy fancy restaurants, choices a and c can be ruled out. Choice b, although casual, doesn’t sound as though it would be the kind of special and memorable evening that Eileen is looking for. Choice d, which is owned by a former baseball star and is described as “charming” and “reminiscent of a baseball clubhouse”, sounds perfect for Eileen’s husband, who is described as a baseball fan and a man with simple tastes.

She also has an olive complexion. Actress #4 is of very slight build and is in her early thirties. She also has blue eyes.

Coding-Decoding:

1. If TAP is coded as SZO, then how is FREEZE coded?

A. ATSSTS
B. EQDDYD
C. ESDDYD
D. EQDDZD

Explanation:

Clearly,
T -1 = S
A -1 = Z
P -1 = O
So FREEZE will be,
F -1 E
R -1 Q
E -1 D
E -1 D
Z -1 Y
E -1 D

2. In a certain code, SIKKIM is written as THLJJL, how is TRAINING written in that code ?

A. SQBHOHOF
B. UQBHOIOF
C. UQBHOHOI
D. UQBHOHOF

Explanation:

In given word, word is increasing and decreasing by one alternatively as,
S +1 T
I -1 H
K +1 L
K -1 J
I +1 J
M -1 L
So in the same way TRAINING will be UQBHOHOF

3. In a certain code, MENTION is written as LNEITNO. How is PATTERN written in that code ?

A. ATAETNR
B. OTAETNR
C. OTAESNR
D. STAETNR

Explanation:

In the given word, we can analyse that,
M is decreased by 1, M-1 = L, and other words are interchanged,
EN – NE
TI – IT
ON – NO
So PATTERN will be
P -1 O
AT – TA
TE – ET
RN – NR

4. In a certain language, MADRAS is coded as NBESBT, how is BOMBAY coded in that code ?

A. CPNCBZ
B. CPNCBX
C. DPNCBZ
D. DPNCBX

Explanation:

Clearly every letter is increased by 1 as
M +1 N
A +1 B
D +1 E
R +1 S
A +1 B
S +1 T
So after increasing every character in work BOMBAY by 1, we get

5. In a certain code, TRIPPLE is written as SQHOOKD. How is DISPOSE written in that code ?

A. EJTQPTF
B. EJTQPTG
C. CHRPNRD

Explanation:

Clearly every letter is decreased by 1.
So DISPOSE will be CHRONRD

Arithmetical Computation:

1. A student got twice as many sums wrong as he got right. If he attempted 48 sums in all, how many did he solve correctly?

A. 12
B. 16
C. 18
D. 24

Explanation:

Suppose the boy got x sums right and 2x sums wrong.
Then, x + 2x = 48
3x = 48
x = 16.

2. In a group of cows and hens, the number of legs is 14 more than twice the number of heads. The number of cows is

A. 5
B. 7
C. 10
D. 12

Explanation:

Let the number of cows be x and the number of hens be y.
Then, 4x + 2y = 2 (x + y) + 14
4x + 2y = 2x + 2y + 14
2x = 14
x = 7.

3. A father tells his son, “I was of your present age when you were born”. If the father is 36 now, how old was the boy five years back?

A. 13
B. 15
C. 17
D. 20

Explanation:

Let the father’s age be x and the son’s age be y.
Then, x – y = y or x = 2y,
Now, x = 36. So, 2y = 36 or y = 18.
Therefore Son’s present age = 18 years.
So, son’s age 5 years ago = 13 years.

4. In a family, a couple has a son and a daughter. The age of the father is three times that of his daughter and the age of the son is half of that of his mother. The wife is 9 years younger to her husband and the brother is seven years older than his sister. What is the age of the mother?

A. 40 years
B. 45 years
C. 50 years
D. 60 years

Explanation:

Let the daughter’s age be x years.
Then, the father’s age = (3x) years.
Mother’s age = (3x – 9) years; Son’s age = (x + 7) years.
So, x + 7 = $$\frac{(3x-9)}{2}$$
2x + 14 = 3x – 9
x = 23.
Therefore Mother’s age = (3X – 9) = (69 – 9)
years = 60 years.

5. Find the number which when added to itself 13 times, gives 112.

A. 7
B. 8
C. 9
D. 11
