Coding And Decoding - General Inteligence & Reasoning MCQ Questions and Answers

D is used for F.
G is used for I.
P is used for R.
and
C is used for E. Thus, it is clear that each letter of the word FIRE stands for each corresponding letter of the coded word DGPC two places ahead. By applying the same principle, the letters QFMR will stand for SHOT. Hence, the last letter of the coded word is R.

By, comparing letters and digit, we get
T = 1
O = 2
U = 3
R = 4
C = 5
L = 6
E = 7
A = 8
S = 9 and
P = 0
As the 5^th letter is SCULPTURE is P and '0' is used for P, therefore, 5th digit is the required code which is '0'.

In the given code

PROSE = PPOQE

The first, third and fifth letters are same but in the place of second and fourth letters previous two letters are used. So,
LIGHT = LGGFT.

Let's break down this Coding and Decoding question step by step.

The question gives us a coded word: SUMMER is coded as RUNNER.
We need to find the code for WINTER using the same rule.

Let's compare SUMMER and RUNNER letter by letter to find the pattern:

S U M M E R
R U N N E R

1. Look at the first letter:
In SUMMER, the first letter is S.
In RUNNER, the first letter is R.
If you go one letter back in the alphabet from S, you get R. (S - 1 = R)

2. Look at the second letter:
In SUMMER, the second letter is U.
In RUNNER, the second letter is U.
The letter U remains unchanged.

3. Look at the third letter:
In SUMMER, the third letter is M.
In RUNNER, the third letter is N.
If you go one letter forward in the alphabet from M, you get N. (M + 1 = N)

4. Look at the fourth letter:
In SUMMER, the fourth letter is M.
In RUNNER, the fourth letter is N.
Again, the letter M changes to N. (M + 1 = N)

5. Look at the fifth letter:
In SUMMER, the fifth letter is E.
In RUNNER, the fifth letter is E.
The letter E remains unchanged.

6. Look at the sixth letter:
In SUMMER, the sixth letter is R.
In RUNNER, the sixth letter is R.
The letter R remains unchanged.

So, the rule for coding is:
1st letter: -1 (go one letter back)
2nd letter: No change
3rd letter: +1 (go one letter forward)
4th letter: +1 (go one letter forward)
5th letter: No change
6th letter: No change

Now let's apply this same rule to the word WINTER:

1. W (1st letter): Apply -1 rule. W - 1 = V
2. I (2nd letter): Apply no change rule. I = I
3. N (3rd letter): Apply +1 rule. N + 1 = O
4. T (4th letter): Apply +1 rule. T + 1 = U
5. E (5th letter): Apply no change rule. E = E
6. R (6th letter): Apply no change rule. R = R

Combining these letters, the code for WINTER is VIOUER.

Let's check the options:
Option A: SUITER
Option B: VIOUER
Option C: WALKER
Option D: SUFFER

Our calculated code VIOUER matches Option B.

Therefore, the correct answer is Option B: VIOUER.

MIND = KGLB

Each letter in the word is moved two steps backward to obtain the corresponding letter of the code. So,

DIAGRAM = BGYEPYK.

PRACTICE = PICCTRAE.
First and last letters are same but second and third letters and third last and second last letters have been interchanged.
So,
FLAMES = FMELAS.

First, let's figure out the rule for how KNIFE becomes MPKHG.
We compare each letter from the first word to the second word:
K is changed to M
(If you count in the alphabet: K, L, M. So, K + 2 letters = M)

N is changed to P
(N, O, P. So, N + 2 letters = P)

I is changed to K
(I, J, K. So, I + 2 letters = K)

F is changed to H
(F, G, H. So, F + 2 letters = H)

E is changed to G
(E, F, G. So, E + 2 letters = G)

So, the secret rule (code) is: Each letter is shifted forward by 2 positions in the alphabet.

Now, we need to find what the letters DTGCF stand for. Since DTGCF is the coded word, to find the original word, we need to do the opposite of the coding rule.
If coding was "+2", then decoding will be "-2" (shifting each letter backward by 2 positions).

Let's apply this rule to DTGCF:
D - 2 letters = B (Counting backward: D, C, B)
T - 2 letters = R (Counting backward: T, S, R)
G - 2 letters = E (Counting backward: G, F, E)
C - 2 letters = A (Counting backward: C, B, A)
F - 2 letters = D (Counting backward: F, E, D)

Putting these decoded letters together, we get BREAD.

Therefore, the letters DTGCF stand for BREAD.
Looking at the options, Option B: BREAD is the correct answer.

First, let's analyze the given coding:
We are told that GBOQX stands for HAPPY.
This implies that GBOQX is the coded form of the original word HAPPY.

Let's find the rule by comparing each letter from the Coded Word (GBOQX) to its corresponding letter in the Original Word (HAPPY):
1. For the first letter:
G (from GBOQX) corresponds to H (from HAPPY)
This transformation is G + 1 = H (moving one step forward in the alphabet).

2. For the second letter:
B (from GBOQX) corresponds to A (from HAPPY)
This transformation is B - 1 = A (moving one step backward in the alphabet).

3. For the third letter:
O (from GBOQX) corresponds to P (from HAPPY)
This transformation is O + 1 = P (moving one step forward).

4. For the fourth letter:
Q (from GBOQX) corresponds to P (from HAPPY)
This transformation is Q - 1 = P (moving one step backward).

5. For the fifth letter:
X (from GBOQX) corresponds to Y (from HAPPY)
This transformation is X + 1 = Y (moving one step forward).

So, the consistent pattern for transforming a Coded Word to its Original Word is: +1, -1, +1, -1, +1.

Now, the question asks: "for which word the letters CROSS stand for ?"
This means we need to find the coded form of the original word CROSS.
To do this, we need to apply the inverse rule of what we found (Coded to Original).
If the rule for Coded to Original is (+1, -1, +1, -1, +1), then the rule for Original Word to Coded Word will be the exact opposite operations for each position.
The inverse rule for Original Word to Coded Word is: -1, +1, -1, +1, -1.

Let's apply this inverse rule to the original word CROSS:
1. For the first letter C: C - 1 = B
2. For the second letter R: R + 1 = S
3. For the third letter O: O - 1 = N
4. For the fourth letter S: S + 1 = T
5. For the fifth letter S: S - 1 = R

Combining these transformed letters, the coded word for CROSS is BSNTR.

Comparing this result with the given options:
Option A: BSPTR
Option B: BSNTR
Option C: BNSTR
Option D: BSNRT

The correct answer is Option B: BSNTR.

we have, S = 5
I = 3
T = 3
E = 0
R = 1
U = 8
N = 4
C = 6
L = 7
B = 1
O = 2
Y = 9.
So,
SON = 524.

H = 1
A = 3
R = 5
D = 7
S = 2
O = 4
F = 6
T = 8.
Hence,
21448 = SHOOT.
