If NATURE is coded as MASUOE, how will be FAMINE decoded as
- A.
GAMIRE
- B.
EALIME
- C.
FAMIQE
- D.
GAOIPE
Correct Answer
B. EALIMEExplanation
The given question follows a pattern where each alternate letter in the word "NATURE" is shifted one position back in the alphabet. Applying the same pattern to the word "FAMINE", each alternate letter should be shifted one position backward, resulting in "EALIME". Therefore, the correct answer is "EALIME".Rate this question:

If HUMBLE is coded as IVNAKD then SIMPLE will be coded as
- A.
RHLOMF
- B.
TJNKOD
- C.
RILQNF
- D.
None
Correct Answer
B. TJNKODExplanation
To solve the problem of coding "SIMPLE" in the same way "HUMBLE" is coded as "IVNAKD," we need to understand the pattern or rule used in the coding.
Let's compare each letter in "HUMBLE" with "IVNAKD":
H -> I (H+1 = I)
U -> V (U+1 = V)
M -> N (M+1 = N)
B -> A (B-1 = A)
L -> K (L-1 = K)
E -> D (E-1 = D)
From this, we can see a pattern:
For the first three letters, each letter is shifted forward by 1 in the alphabet.
For the last three letters, each letter is shifted backward by 1 in the alphabet.
Using this pattern, let's code "SIMPLE":
S -> T (S+1 = T)
I -> J (I+1 = J)
M -> N (M+1 = N)
P -> O (P-1 = O)
L -> K (L-1 = K)
E -> D (E-1 = D)
So, "SIMPLE" will be coded as "TJNKOD".Rate this question:

If SHELNXR stands for TEDIOUS, in the same way how would GLAMOUR be coded?
- A.
FODPNUQ
- B.
FOBPNXS
- C.
HIZJPRS
- D.
FODPNUS
Correct Answer
C. HIZJPRSExplanation
To determine how GLAMOUR would be coded, we need to identify the pattern used to encode SHELNXR as TEDIOUS. Let's analyze the pattern by comparing each corresponding letter:
S → T H → E E → D L → I N → O X → U R → S
Now let's break down the shifts:
S to T: +1
H to E: -3
E to D: -1
L to I: -3
N to O: +1
X to U: -3
R to S: +1
The pattern alternates between adding 1 and subtracting 3:
+1
-3
-1
-3
+1
-3
+1
Now, let's apply this pattern to GLAMOUR:
G (+1) → H
L (-3) → I
A (-1) → Z
M (-3) → J
O (+1) → P
U (-3) → R
R (+1) → S
So, the code for GLAMOUR would be HIZJPRS.Rate this question:

If LCMHN represents MANGO, then how will BOUTS be represented?
- A.
CMVST
- B.
APTUP
- C.
AQTVQ
- D.
AQUVR
Correct Answer
A. CMVSTExplanation
To solve this type of encoding puzzle, let's analyze how LCMHN is transformed into MANGO.
Let's break it down letter by letter:
L -> M
C -> A
M -> N
H -> G
N -> O
By comparing the positions of the letters in the alphabet:
L is the 12th letter, and M is the 13th letter (L + 1 = M)
C is the 3rd letter, and A is the 1st letter (C - 2 = A)
M is the 13th letter, and N is the 14th letter (M + 1 = N)
H is the 8th letter, and G is the 7th letter (H - 1 = G)
N is the 14th letter, and O is the 15th letter (N + 1 = O)
The transformation pattern seems to be:
+1, -2, +1, -1, +1
Now, applying the same pattern to BOUTS:
B -> C (B + 1)
O -> M (O - 2)
U -> V (U + 1)
T -> S (T - 1)
S -> T (S + 1)
Therefore, BOUTS would be represented as CMVST.Rate this question:

If ANNJ is for BOOK, then what code will be for LOOK?
- A.
KONJ
- B.
INNK
- C.
KNMJ
- D.
KNNJ
Correct Answer
D. KNNJExplanation
The code for each letter in the word ANNJ is obtained by shifting the corresponding letter in the word BOOK one position to the right in the alphabet. Applying the same logic to the word LOOK, the letter L would be shifted to N, O to N, O to J, and K to J. Therefore, the code for LOOK would be KNNJ.Rate this question:

If RTTHHX encodes for purify, then code for BLANCH will be:
- A.
DKDSHG
- B.
AOCGTY
- C.
DKCMEG
- D.
EMGCKD
Correct Answer
C. DKCMEGExplanation
The given question involves encoding a word using a specific code. The code for "purify" is given as "RTTHHX". To find the code for "BLANCH", we need to find a pattern in the given code. Upon observation, it can be seen that each letter in the code is shifted forward by one position in the alphabet. Applying the same pattern to "BLANCH", we get "DKCMEG" as the code.Rate this question:

If BAT stands for CDQ then PEN stands for
- A.
QIK
- B.
PHK
- C.
QHK
- D.
QHJ
Correct Answer
C. QHKExplanation
The given question follows a pattern where each letter in the word BAT is replaced by the corresponding letter that is three positions ahead in the alphabet. Applying this pattern to the word PEN, we get the letters QHK. Therefore, the correct answer is QHK.Rate this question:

NUST is coded as MWPS, then GIKI can be decoded as
- A.
GLJJ
- B.
FHJL
- C.
HFOJ
- D.
HKIJ
Correct Answer
B. FHJLExplanation
This is a letter-shifting code where each letter in the original word is replaced with the letter that comes before it in the alphabet.
NUST: N -> M, U -> T, S -> R, T -> S, resulting in MWPS
Applying the same pattern to GIKI:
GIKI: G -> F, I -> H, K -> J, I -> L, resulting in FHJLRate this question:

If in a certain language SHIFT is coded as RFFPO, which word would be coded as LKUMB
- A.
MMXCG
- B.
MLVNC
- C.
KJVLA
- D.
MJVLC
Correct Answer
A. MMXCGExplanation
In the given language, each letter of the word is shifted by a certain number of positions to obtain the coded word. By observing the given examples, it can be deduced that the first letter is shifted by 1 position, the second letter by 2 positions, the third letter by 3 positions, and so on. Applying the same pattern, the word "LKUMB" would be coded as "MMXCG" because L is shifted by 1 position to become M, K is shifted by 2 positions to become M, U is shifted by 3 positions to become X, M is shifted by 4 positions to become C, and B is shifted by 5 positions to become G.Rate this question:

If SPIDER is written as PSDIRE in a certain code, how would COMMON be written in that code
- A.
OCMMON
- B.
OCMOMN
- C.
OCOMMO
- D.
OCMMNO
Correct Answer
D. OCMMNOExplanation
The code appears to be reversing the letters in the word and then rearranging them. In the word "SPIDER," the letters are reversed to spell "REDIPS," and then rearranged to form "PSDIRE." Applying the same pattern to the word "COMMON," the letters are reversed to spell "NOMMOC," and then rearranged to form "OCMMNO."Rate this question:

GAMBLE is coded as FBLCKF, how is FLOWER coded in that code
- A.
GKPVFQ
- B.
GMPVDS
- C.
EMNXDS
- D.
EKNVDQ
Correct Answer
C. EMNXDSExplanation
The code for each letter in the word "GAMBLE" is obtained by shifting it one position to the left in the alphabet. Applying the same logic to the word "FLOWER", each letter should be shifted one position to the left. Therefore, the correct code for "FLOWER" is "EMNXDS".Rate this question:
