Understanding the Coding Pattern
The question asks us to decode the pattern used to code the word CRAFT as $5-21-3-9-22$ and then apply this pattern to code the word ORDER.
First, let's determine the standard position of each letter in the English alphabet:
- A = 1, B = 2, C = 3, ..., Z = 26.
Now, let's find the alphabetical positions for the letters in CRAFT:
- C is the 3rd letter.
- R is the 18th letter.
- A is the 1st letter.
- F is the 6th letter.
- T is the 20th letter.
Let's compare these positions with the given code ($5-21-3-9-22$):
| Letter | Alphabetical Position | Given Code | Difference | Operation |
|---|---|---|---|---|
| C | 3 | 5 | $5 - 3 = 2$ | $3 + 2 = 5$ |
| R | 18 | 21 | $21 - 18 = 3$ | $18 + 3 = 21$ |
| A | 1 | 3 | $3 - 1 = 2$ | $1 + 2 = 3$ |
| F | 6 | 9 | $9 - 6 = 3$ | $6 + 3 = 9$ |
| T | 20 | 22 | $22 - 20 = 2$ | $20 + 2 = 22$ |
We can observe a pattern in the operation applied:
- The 1st letter (C) has 2 added to its position ($3 + 2 = 5$).
- The 2nd letter (R) has 3 added to its position ($18 + 3 = 21$).
- The 3rd letter (A) has 2 added to its position ($1 + 2 = 3$).
- The 4th letter (F) has 3 added to its position ($6 + 3 = 9$).
- The 5th letter (T) has 2 added to its position ($20 + 2 = 22$).
The pattern is to add 2 to the alphabetical position for letters at odd positions in the word (1st, 3rd, 5th, etc.) and add 3 to the alphabetical position for letters at even positions in the word (2nd, 4th, 6th, etc.).
Coding the Word ORDER
Now, we apply this pattern to the word ORDER.
First, find the alphabetical positions of the letters in ORDER:
- O is the 15th letter.
- R is the 18th letter.
- D is the 4th letter.
- E is the 5th letter.
- R is the 18th letter.
Apply the pattern (+2 for odd positions, +3 for even positions):
- O (1st letter - odd position): Alphabetical position = 15. Operation: Add 2. Calculated code: $15 + 2 = 17$.
- R (2nd letter - even position): Alphabetical position = 18. Operation: Add 3. Calculated code: $18 + 3 = 21$.
- D (3rd letter - odd position): Alphabetical position = 4. Operation: Add 2. Calculated code: $4 + 2 = 6$.
- E (4th letter - even position): Alphabetical position = 5. Operation: Add 3. Calculated code: $5 + 3 = 8$.
- R (5th letter - odd position): Alphabetical position = 18. Operation: Add 2. Calculated code: $18 + 2 = 20$.
Combining these results, the code for ORDER is $17-21-6-8-20$.
| Letter | Position in Word | Alphabetical Position | Operation | Resulting Code |
|---|---|---|---|---|
| O | 1st (Odd) | 15 | $+ 2$ | $15 + 2 = 17$ |
| R | 2nd (Even) | 18 | $+ 3$ | $18 + 3 = 21$ |
| D | 3rd (Odd) | 4 | $+ 2$ | $4 + 2 = 6$ |
| E | 4th (Even) | 5 | $+ 3$ | $5 + 3 = 8$ |
| R | 5th (Odd) | 18 | $+ 2$ | $18 + 2 = 20$ |
This result corresponds to option 4.
Important Questions from Coding Decoding (Notes)
- In a certain code language, "in the end" means "moh fjk omt", "end is near" means "azh moh bod" and "in near future" means "omt azh epy". What will be the code for "near"?
- In a certain code, 'BASKET' is written as '5$3%#1' and 'TRIED' is written as '14$\star$#2'. How will 'SKIRT' be written in that code?
- In a certain code language:
'Logical Reasoning Exam' is written as 'G12 I7 D13'.
