In a certain code language, 'PEARL' is coded as '24153', 'EARTH' is coded as '41590' and 'PILE' is coded as '2634'. What is the code for the word 'HEAR' in that language?
0415
Decoding the Code Language: Finding the Code for HEAR
This problem involves a simple substitution code where each letter corresponds to a unique digit. We are given the codes for three words: 'PEARL', 'EARTH', and 'PILE'. By comparing the codes and the letters in these words, we can deduce the code assigned to each individual letter.
Analyzing the Given Codes
Let's look at the provided codes:
- PEARL is coded as 24153
- EARTH is coded as 41590
- PILE is coded as 2634
Identifying Letter Codes
We can compare the words and their codes to find the value of each letter. Notice that letters common to multiple words appear with the same digit code.
| Word | Code | Letters and Potential Codes |
|---|---|---|
| PEARL | 24153 | P=2, E=4, A=1, R=5, L=3 |
| EARTH | 41590 | E=4, A=1, R=5, T=9, H=0 |
| PILE | 2634 | P=2, I=6, L=3, E=4 |
By observing the consistent codes across the examples, we can confirm the codes for each letter needed:
- From PEARL and EARTH, E = 4.
- From PEARL and EARTH, A = 1.
- From PEARL and EARTH, R = 5.
- From PEARL and PILE, P = 2.
- From PEARL and PILE, L = 3.
- From EARTH, T = 9.
- From EARTH, H = 0.
- From PILE, I = 6.
So, the individual letter codes we need for the word 'HEAR' are:
- H = 0
- E = 4
- A = 1
- R = 5
Coding the Word 'HEAR'
Now, to find the code for 'HEAR', we simply arrange the codes for its letters in the correct order:
- H corresponds to 0
- E corresponds to 4
- A corresponds to 1
- R corresponds to 5
Putting these together, the code for 'HEAR' is 0415.
| Letter | Code |
|---|---|
| H | 0 |
| E | 4 |
| A | 1 |
| R | 5 |
Therefore, the code for the word 'HEAR' is 0415.
Revision Table: Coding and Decoding
| Concept | Description |
|---|---|
| Letter Coding | Letters are assigned specific codes, often other letters, numbers, or symbols. |
| Direct Substitution | Each letter in the original word is replaced by a specific, fixed code. |
| Pattern Recognition | Identifying the rule or logic behind the coding pattern by comparing given examples. |
| Deduction | Using the given information to deduce unknown codes for individual letters or groups. |
Additional Information: Types of Coding-Decoding Questions
Coding-decoding questions are common in reasoning sections of competitive exams. They test your ability to understand a pattern and apply it. Some common types include:
- Letter Coding: Letters are coded using other letters based on position in the alphabet, skipping letters, or substitution.
- Number Coding: Words are coded using numbers based on the position of letters, sum of positions, or other numerical rules.
- Symbol Coding: Letters or words are coded using symbols.
- Mixed Coding: Words, numbers, and symbols are used together in a coded message.
- Sentence Coding: A few sentences are given with their coded versions, and you need to decode a specific word or sentence.
Solving these problems usually involves carefully observing the given examples, identifying the rule, and applying it to the new word or message.
