Question 1
If DRIVE is coded as 59372, and SPUR is coded as 6489, what will be code for PRIDE ?
The pattern followed here is:
| Letter | D | R | I | V | E |
| Code | 5 | 9 | 3 | 7 | 2 |
Â
| Letter | S | P | U | R | Â |
| Code | 5 | 9 | 3 | 7 | Â |
Similarly,
| Letter | P | R | I | D | E |
| Code | 4 | 9 | 3 | 5 | 2 |
Hence, the correct answer is ‘49352’

Question 3
If TEMPLE is coded as ELPMET, then how will CHURCH be coded as ?
The given code appears to be reversing the letters in the word. For example, in "TEMPLE," the letters are reversed to form "ELPMET."
Applying the same pattern to "CHURCH":
- "CHURCH" is reversed to "HCRUHC."
So, "CHURCH" will be coded as "HCRUHC."
The correct option is:
B. HCRUHC

Question 4
In a certain language, CADET is written as 31457. How will DEFER be written as in the same language ?
To decode the word "CADET" to "31457," it seems each letter is being replaced with a corresponding number based on its position in the English alphabet. Here's the decoding:
- C -> 3
- A -> 1
- D -> 4
- E -> 5
- T -> 7 (Counting from the reverse direction)
Now, applying the same pattern to "DEFER":
- D -> 4
- E -> 5
- F -> 6
- E -> 5
- R -> 9 (Counting from the reverse direction)
So, "DEFER" will be written as "45659."
The correct option is:
45659

Question 5
If ‘ARUN’ is coded as 54, then how will ‘VARUN’ be coded as ?
| Letter | A | B | C | D | E | F | G | H | I | J | K | L | M |
| Number | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| Letter | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
| Number | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
To decode the word "ARUN" to "54," we can assume that each letter is being assigned a numerical value, and then the values are combined. Here's how it might work:
- A -> 1
- R -> 18
- U -> 21
- N -> 14
1 + 18 + 21 + 14 = 54
Now, applying the same pattern to "VARUN":
- V -> 22
- A -> 1
- R -> 18
- U -> 21
- N -> 14
22 + 1 + 18 + 21 + 14 = 76
The correct option is:
76

Question 6
If MADE is coded as 12236 and BAD is coded as 123, then how will DECK be coded as ?
| Letter | A | B | C | D | E | F | G | H | I | J | K | L | M |
| Number | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| Letter | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
| Number | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
Â
Pattern: The subscripts are the positional value of the letter
Â
Thus MADE = 12236
Similarly, BAD is coded as 123 because
Therefore, DECK is decoded as:
Thus the correct option is A. 36212

Question 7
In a code language, MACHINE is written as CAMHENI. How will MONSTER be written as in that language ?
The pattern is to swap the position of the first two letters, then the next three letters and finally the last two letters.
MACHINE → CAMHENI
Thus,
MONSTER → NOMSRET
Therefore the correct answer is A

Question 8
In a code language, EXPLAIN is written as XEALPNI. How will FACTORY be written in that language ?
The pattern is to swap the position of the first two letters, then the next three letters and finally the last two letters.
EXPLAIN → XEALPNI
Thus,
FACTORY → AFOTCYR
Therefore, the correct answer is C

Question 9
In a certain code language ‘EXAMPLE’ is coded as ‘DWZLOKD’. Then how will ‘ELECTION’ be coded in the same code language ?
The pattern ifollows a left shift in the alphanetical position.
Â
| Letter | E | X | A | M | P | L | E | Â |
| Shift | -1 | -1 | -1 | -1 | -1 | -1 | -1 | Â |
| New letter | D | W | Z | L | O | K | D | Â |
| Letter | E | L | E | C | T | I | O | N |
| Shift | -1 | -1 | -1 | -1 | -1 | -1 | -1 | Â |
| New letter | D | K | D | B | S | H | N | M |
Therefore, the correct answer is B. DKDBSHNM

Question 10
In a code language, TANK is written as 7-26-13-16. How will CARGO be written in that language ?
The pattern ifollows a left shift in the alphanetical position.
| Letter | A | B | C | D | E | F | G | H | I | J | K | L | M |
| Position | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| Positon | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 |
| Letter | Z | Y | X | W | V | U | T | S | R | Q | P | O | N |
In reverse order:
T → 7
A → 26
N → 13
K → 16
Similarly:
C → 24
A → 26
R → 9
G → 20
O → 12
Therefore, the correct option is: 24-26-9-20-12
