In a code language, 'BANYAN' is written as 'EDQBDQ' and 'LAUNCH' is written as 'ODXQFK'. How will 'STRIKER' be written in that language?
VWULNHU
Understanding the Coding Decoding Logic
This question is based on coding-decoding, a common type of logical reasoning problem. We are given two examples of words coded into a new form, and we need to find the pattern or rule used for coding. Once the rule is identified, we apply it to a new word to find its coded form.
Analyzing the Given Examples
Let's examine the first pair of words:
- Original Word: BANYAN
- Coded Word: EDQBDQ
Let's look at the transformation of each letter:
- B to E
- A to D
- N to Q
- Y to B
- A to D
- N to Q
Now, let's consider the position of these letters in the English alphabet (A=1, B=2, ..., Z=26):
| Original Letter | Position | Coded Letter | Position | Change |
|---|---|---|---|---|
| B | 2 | E | 5 | +3 |
| A | 1 | D | 4 | +3 |
| N | 14 | Q | 17 | +3 |
| Y | 25 | B | 2 | +3 (25+3=28, which wraps around to 2 in a 26-letter alphabet) |
| A | 1 | D | 4 | +3 |
| N | 14 | Q | 17 | +3 |
It appears that each letter in the original word is shifted forward by 3 positions in the alphabet to get the coded letter. The shift wraps around from Z to A.
Let's verify this rule with the second pair of words:
- Original Word: LAUNCH
- Coded Word: ODXQFK
Applying the "+3 shift" rule:
- L (12) + 3 = O (15) - Correct
- A (1) + 3 = D (4) - Correct
- U (21) + 3 = X (24) - Correct
- N (14) + 3 = Q (17) - Correct
- C (3) + 3 = F (6) - Correct
- H (8) + 3 = K (11) - Correct
The rule is consistent: each letter is shifted forward by 3 positions in the alphabet.
Applying the Rule to 'STRIKER'
Now we will apply the same "+3 shift" rule to the word 'STRIKER'.
- S: S is the 19th letter. 19 + 3 = 22. The 22nd letter is V.
- T: T is the 20th letter. 20 + 3 = 23. The 23rd letter is W.
- R: R is the 18th letter. 18 + 3 = 21. The 21st letter is U.
- I: I is the 9th letter. 9 + 3 = 12. The 12th letter is L.
- K: K is the 11th letter. 11 + 3 = 14. The 14th letter is N.
- E: E is the 5th letter. 5 + 3 = 8. The 8th letter is H.
- R: R is the 18th letter. 18 + 3 = 21. The 21st letter is U.
So, 'STRIKER' is coded as 'VWULNHU'.
Comparing with Options
Let's compare our result with the given options:
- VWULNHU
- SCFIRET
- ELBURPT
- UNDARSA
Our calculated coded word 'VWULNHU' matches the first option.
Revision Table: Coding Logic Summary
| Original Word | Coded Word | Rule Applied |
|---|---|---|
| BANYAN | EDQBDQ | Each letter +3 (with wrap-around Z to A) |
| LAUNCH | ODXQFK | Each letter +3 (with wrap-around Z to A) |
| STRIKER | VWULNHU | Each letter +3 (with wrap-around Z to A) |
Additional Information: Types of Letter Coding
Coding-decoding questions often involve rules related to letters. Some common types of letter coding include:
- Shift Coding: Each letter is shifted a fixed number of positions forward or backward in the alphabet. (This is the type used in this question).
- Reverse Order Coding: The letters of the word are reversed.
- Direct Letter Coding: Each letter is assigned a specific code letter, and the mapping is fixed.
- Positional Value Coding: The code is based on the alphabetical position of letters.
- Mixed Coding: A combination of different rules.
To solve these questions, it's important to carefully observe the patterns in the given examples, such as letter shifts, letter positions, or specific letter substitutions.
Important Questions from Coding and Decoding By Letter Shifting
In a certain code language, 'MANGOES' is written as 'AEGMNOS'. How will 'FRIEND' be written in that language?
In a certain code language, ‘SPIRIT’ is written as ‘WKMIMG’. How will ‘GLOBAL’ be written in that language?
In a certain code language, ‘ABSTRACT’ is written as ‘IIYYVDEU’. How will ‘INSTINCT’ be written in that language?
In a certain code language, 'LUCKNOW' is written as 'CULKWON' and 'UDAIPUR' is written as 'ADUIRUP'. How will 'GWALIOR' be written in that language?
If in a code language ADVENTURES is coded as VDANEUTSER, then SYSTEMATIC would be coded as:
