Answer & Explanations
1. Option (d). Exp: In first two positions of dice one common face containing 5 is same. Therefore
according to rule no. (3) the face opposite to the face which contains 2 point, will contains 6 points.
2. Option (a). Exp: The colours adjacent to yellow are orange, blue, red and rose. Hence violet will be
opposite to yellow.
3. Option (c). Exp: According to the rule no. (3), common faces with number 3, are in same positions.
Hence the number of the opposite face to face with number 5 will be 6.
4. Option (c). Exp: Even numbered dice are: (II), (IV) and (VI)
No. of dots on the top face of (II) dice = 6
No. of dots on the top face of (IV) dice = 6
and No. of dots on the top face of (VI) dice = 6
Therefore Required total = 6 + 6 + 6 = 18
5. Option (a). Exp: Odd numbered dice are : (II), (III) and (V)
No. of dots on the top faces of these dice are 2, 2 and 4 respectively.
Required total = 2 + 2 + 4 = 8
6. Option(d). Exp: No. of faces on the top faces of the dice (I), (II) and (III) are 5, 1 and 5 respectively.
Therefore, Total of these numbers = 5 + 1 + 5 = 11
No. of dots on the top faces of the dice (IV), (V) and (VI) are 1, 3 and 1 respectively.
Therefore, Total of these numbers = 1 + 3 + 1 = 5
Required difference = 11 – 5 = 6.
7. Option (c). Exp:
Number of small cubes having only two faces coloured = 6 from the front + 6 from the back + 2 from
the left + 2 from the right = 16.
8. Optin (d). Exp:
Such cubes are related to the corners of the cuboid and there are 8 corners.
Hence, the required number is 8.
9. Option (b). Exp:
Number of small cubes have no face coloured = (4 – 2) x (3 – 2) = 2 x 1 = 2.
10. Option (a). Exp:
Number of small cubes having only one face coloured = 2 x 2 + 2 x 2 + 2 x 1
= 4 + 4 + 2
= 10
Day Sequence Aptitude basics, practice questions, answers and explanations
Prepare for companies tests and interviews
Day sequence Test: In these question a date given with the day of the week (Monday, etc…..) using that information you will be asked to find out day of other date.
Approach:
1)Find the No. of years and No. of days between the “given date” and “asked date”.
2)Divide the No. of days by 7.
3)Find the reminder of the division.
4)If the reminder is ‘0’ then the required day is as same as “given days”.
5)If the reminder is ‘1’ then the required day is the next day to given day in question date?
6)If the reminder is ‘2’ then the required day is two days after the “given date”, so on for the 3, 4, 5 and 6 reminders.
Examples:
1) If 15th August is Monday, 17th November comes on which day?
Answer: August month has 31 day, September has 30 days and October has 31 days.
The number of days between 15th August to 17th November= 16 + 30 + 31 + 17= 94.
94/7, it leaves reminder 3. 17th November= 3 days after Monday.
i.e. Thursday.
2) If 7th February of 2006 is Saturday, 24th April 2006 comes on which day?
Answer: 2006 is not a leap year, so February has 28 days, March 2006 has 31 days.
The No. of days between 7th February 2006 to 24th April 2006 = 21 + 31 + 24 = 76.
76/7, it leaves reminder 6, 24 th April 2006 = 6 days after Saturday = Friday.
3) 14th December 2004 is Monday, 25th November 2005 comes on which day?
Answer: The No. of days between 14th December 2004 to 25 th November 2005 = 365 – 19 (days gap between 14th December to 25 th November = 19 and 2005 is a normal year) = 346.
346/7, it leaves reminder 3; 25th November 2005 = 3 days after Monday = Thursday.
4) If 26th March 2006 is Friday, 18th May 2008 is comes on which day?
Answer: Days between Step 1 : from 26th March 2006 to 25th March 2007 – 365 days
Step 2 : from 26 th March 2007 to 25 th March 2008 – 366 days 26 th March 2008 to 18 th May 2008 = 31 + 22 = 53 days Total days = 365 + 366 + 53 = 784.
784/7 = 112, it leaves no reminder.
18th May 2008 is also Friday.
Tips:
A year has 365 days
A leap year has 366 days
Any year is divisible by 4 is a leap year e.g. 2004, 2008,…….
In normal year, February has 28 days but leap year has 29 days. Hence the leap year has one day extra than normal year.
In a normal year, if the year begins with Sunday, it ends with Sunday. The next year starting day will be Monday.
In a Leap year, if the year begins with Sunday, it ends with Monday, the starting day of the next year of the leap year will be Tuesday.
The no. of days in January = 31 days
The no. of days in February = 28 or 29 days
The no. of days in March = 31 days
The no. of days in April = 30 days
The no. of days in May = 31 days
The no. of days in June = 30 days
The no. of days in July = 31 days
The no. of days in August = 31 days
The no. of days in September = 30 days
The no. of days in October = 31 days
The no. of days in November = 30 days
The no. of days in December = 31 days
In a normal year, it has 52 weeks and one day
In a leap year, it has 52 weeks and 2 days.
For every 400 years, the day repeats. e.g. 14th April 1604 is Wednesday, 14th April 2004 is also Wednesday.

PROCESSOR is coded as D4F3C5C1E1S1S1E3C6
a. QUADRANT
 Q1C7A1B2F6A1B7E4

b. WINDOW
 W1E4B7B2E3W1
 W1C3B7B2E3W1
 W1C3B7B2C3W1
 W1C3G7B2E3W1
Answer & Explanations
1. Exp: Word: M U S E U M
Logic: 1 2 3 4 5 6
Code: L S P A P G
Similarly, the code for PALACE is
Word: P A L A C E
Logic: 1 2 3 4 5 6
Code: O Y I W X Y
2. Exp: The alphabets are coded as follows:
D E L H I C A U T
7 3 5 4 1 8 2 9 6
So, in CALICUT, C is coded as 8, A as 2, L as 5, U as 9 and T as 6. Thus, the code for CALICUT is
8251896.
3. Exp: The code for the word DANCE is 21211.
4. Exp: Number of letters in the word CONTRACT = 8 and 8 x 7 = 56.
Number of letters in the word GROWTH = 6 and 6 x 5 = 30.
Similarly, DISTRIBUTION => 12 and 12 x 11 = 132.
5. Exp: In this product of the digits in the placevalues of the letters as per the alphabet is obtained
first and then added i.e, BLOCK
=> B = 2
L = 12 => 1 x 2 = 2
O = 15 => 1 x 5 = 5
C = 3
K = 11 => 1 x 1 = 1
Now (2 + 2 + 5 + 3 + 1) = 13.
So, BLOCK = 13.
Similarly, SCIENCE = 38.
6. Exp: In this coding, the letters from either end of the word are written, first a letter from the right
end and then a letter from the left end of the word and so on. Hence DISTANCE is coded as
EDCINSAT.
Similarly, ACQUIRE is coded as EARCIQU.
7. Exp: It is given that 28 + 14 = 50 => (2 + 8) x (1 + 4)
=> 10 x 5 = 50 and 36 + 43 = 63 => (3 + 6) x (4 + 3)
=> 9 x 7 = 63 then 44 + 52 => (4 + 4) x (5 + 2) => 8 x 7 = 56.
8. Exp: 14 x 15 = 14 + 15 = 29 and 29 – 4 = 25.
26 x 42 = 26 + 42 = 68 and 68 – 4 = 64.
Similarly, 73 x 31 = (73 + 31) – 4 = 104 – 4 = 100.
9. Exp: In the first and second statements, the common code word is ‘kew’ and the common word is
‘she’. So, ‘kew’stands for ‘she’.
In the first and third statements, the common code word is ‘deko’ and the common word is
‘apples’. So, ‘deko’stands for ‘apples’.
10. a. Exp: PROCESSOR =>
P = 16 and D4 => 4 x 4 = 16 = P
R = 18 and F3 => 6 x 3 = 18 = R
O = 15 and C5 => 3 x 5 = 15 = O and so on.
Hence, PROFESSOR is coded as D4F3C5C1E1S1S1E3C6.
QUADRANT is coded as Q1C7A1B2F3A1B7E4.
b. Exp: WINDOW is coded as W1C3B7B2E3W1.

10. Find the wrong term in the letternumber series given below:
G4T, J10R, M20P, P43N, S90L
a. G4T
b. J10R
c. M20P
d. P43N
e. S90L
Answer & Explanations
1. The numbers are (x*1)1; (x2)2; (x3)3….
Hence the series would be (32*5)5=155
2. The pattern is 8^{2 }(?) 2^{2}; ?= 8+2=10^{2}= 100
3. The pattern is get by adding 1.5, 2.5, 3.5 …..
Then, 19+6.5 = 25.5
4. Clearly, 5+3= 8, 8+3= 11, 11+3= 14,….
So this is an A.P series in which a=5, d=3.
Let the number of the terms be n
Then, 320= 5+(n1)*3; 3n=318; n=106
5. This is an G.P series in which a= 5; r= 2
10^{th} term= ar^{(n1)} = 5*2 ^{(101) }= 5*2 ^{9} = 2560
6. Each term in the series consists of three consecutive letters in reverse order. The first letter of each term
and last letter of next term is the same.
7. The letters in each term are moved five steps forward to obtain the corresponding letters of next term.
8. The number of letters in the terms goes on increasing by one at each step. Each term consists of letters
in alphabetic order. The last letter of each term and first letter of next term are alternate.
9. The first and third letters of each term are moved one step backward and the second letter is moved one
step forward to obtain the corresponding letters of the next term.
10. The first letter of each term is moved three steps forward and the last letter is moved two steps
backward to obtain the corresponding letters of the next term. The numbers follow the sequence *2+1,
*2+2, *2+3, *2+4.
So, 10 is wrong and must be replaced by (4*2+1) = 9.
