Question 25: In a certain language, LEGEND is coded as MDHDOC. What is the code for ROCKSTAR?

a) SNDJTSBQ

b) NSDJTSBQ

c) SNDTJSQB

d) SDNJTSBQ The pattern of this series is as below
Z,(Y),X,W,V,U,(T),S,R,Q,P,(O),N,M,L,K,(J),I,H,G,F,(E),C,D,B,A
Four alphabets are being skipped for every consecutive term in the series.
Y,T,O,J,E…..
Hence, E is the next term.

Here, the first letter of the series is the squares of consecutive natural numbers.
Hence, next letter is $4^{2} = 16$
The letter accompanying it will be the 16th alphabet in the alphabet series.
Hence, 16P is the next term.

In this question, the pattern is of consecutive alphabets by skipping two alphabets.
i.e. (KL),MN,(OP),QR,(ST),UV,(WX)………….
Hence, the next term is WX.

The pattern in the given series is as shown below.
1st letter of each term is following the below series
N,M,L,K,J…..
2nd letter of each term is following the below series
O,P,Q,R,S………..
3rd letter of each term is following the below series
C,D,E,F……………
Hence, the following term will be KRF.

Simplifying 147 days into complete weeks and odd days.
147 days = 21 weeks+0 odd days
Hence, After 147 days, it will be Thursday+0 = Thursday.

Simplifying 97 days into complete weeks and odd days.
97 days = 13 weeks+6 odd days.
Hence, After 97 days, it will be Monday+6 = Sunday

Simplifying 86 days into complete weeks and odd days.
86 days = 12 weeks+2 odd days
Hence, After 86 days, it will be Friday+2 = Sunday

Simplifying 122 days into complete weeks and odd days.
122 days = 17 weeks+3 odd days.
Hence, After 122 days, it will be Saturday+3 = Tuesday.

Daughter of Amarjeet’s father = Amarjeet’s sister

Now, the boy is son of Amarjett’s sister, => Amarjeet is the boy’s uncle.

=> The boy is Amarjeet’s nephew.

=> Ans – (A)

It is given that Shyam is the grandfather of Rajendra’s son.

Thus, Rajendra is the son of Shyam.

Thus, Shyam is the father of Rajendra.

=> Ans – (C)

Rahul’s paternal grandfather’s only son is Rahul’s father.

Now, the boy is the brother of daughter of Rahul’s father, => Rahul and the boy are siblings.

Thus, That boy is Rahul’s brother.

=> Ans – (D)

Father of Hemant’s father is = Hemant’s grandfather

Now, Hemant’s grandfather is brother of Sumit’s grandfather.

=> Sumit and Hemant are cousins.

=> Ans – (B)

112 & 16 @ 7 % 9 * 22 = (112 / 16) * 7 – 9 + 22 = (7*7) – 9 + 22 = 40 + 22 = 62
Hence, option C is the right choice.

6 # 29 ^ 2 & 96 ! 4 = 6 + 29 * 2 – 96 / 4 = 6 + 58 – 24 = 40
Hence, option A is the right choice.

15 & 7 % 25 @ 108 # 12 = 15 * 7 + 25 – 108/12 = 105 + 25 – 9 = 121
Hence, option D is the right choice.

13 ! 102 @ 6 % 2 ^ 41 = 13 + [(102 /6) * 2] – 41 = 13 + (17*2) – 41 = 6
Hence, option A is the right choice.

$64 = 4^3$ and $256=4^4$
$27=3^3$
Applying the same logic the number in the place of question mark should be,
$3^4=81$

Let us write the alphabets from A to Z in two rows as shown below. The alphabet B in row 1 corresponds to Y in row 2.
The alphabet E in row 1 corresponds to V in row 2.
The alphabet H in row 1 corresponds to S in row 2.
The alphabet I in row 1 corresponds to R in row 2.
So the word BEHI is written as YVSR.
Applying the same logic “GCMJ” must be written as “TXNQ”.

Here, F,G,H are the alphabets before I,J,K
Hence, the 3 alphabets before P,Q,R are M,N,O
Hence, MNO is the correct answer.

Here, $120 = 11^{2} – 1$
$? = 13^{2}-1$
Hence, $? = 168$

$81 = 9^2$
$144=12^2$
$225=15^2$
Since square root the next term has a difference of 3 with square root of the initial term
$\implies 9^2: 12^2:: 15^2: 18^2$ would be the correct
Hence, the Option B is the answer

The logic involved in coding of the word ‘WORD’ to ‘ZRUG’ is as represented below
W+3 – Z
O+3 – U
R+3 – R
D+3 – G
Similarly, the code for the word ‘WALLET’ is ‘ZDOOHW’.

While coding a given word, the first letter is replaced by the next letter, the second letter is replaced by the previous letter and so on the pattern is followed.
I -> J
M -> L
A -> B
G -> F
I -> J
N -> M
E-> F
Thus the word IMAGINE is coded as JLBFJMF.

Destroy and Create are opposite to one another.
So, ? should be opposite of Sound which is Silence.
Thus, D is the correct answer.

Here, the first letter is replaced by next alphabet and second is replaced by previous alphabet and the same pattern is followed for the entire word.
ROCKSTAR will be coded as below.
R – >S
O -> N
C->D
K-> J
S-> T
T->S
A->B
R->Q
SNDJTSBQ is the code for ROCKSTAR
