Understanding Word Substitution in Logical Reasoning
This question is an example of a word substitution or coding-decoding puzzle often found in logical reasoning sections. In such puzzles, certain words are given new meanings or names, and you need to apply these substitutions to answer a question.
Analyzing the Given Substitutions
We are provided with the following sequence of substitutions:
- If banana is apple
- apple is grapes
- grapes is litchi
- litchi is nuts
- nuts is guava
This means that in this specific context, the word "banana" is used to mean "apple", "apple" is used to mean "grapes", and so on.
Identifying the Yellow Fruit
The question asks which of the given options is a yellow fruit according to these substitutions. First, let's think of a common yellow fruit that might be involved in the substitutions.
A widely known yellow fruit is the banana.
Applying the Substitution Rule
Now, let's look at the substitutions provided. We are told that "banana is apple". This means that what we normally call a "banana" is now referred to as "apple" in this coded language.
Since banana is a yellow fruit, and banana is called apple, the item that is a yellow fruit is now called "apple".
Checking the Options
The options given are:
- Mango
- Guava
- Apple
- Nuts
We determined that, according to the substitutions, the yellow fruit (banana) is called "apple". Looking at the options, "Apple" is one of the choices.
Conclusion
Based on the given word substitutions, the fruit that is yellow (banana) is referred to as "apple". Therefore, among the options, "Apple" represents the yellow fruit in this coded language.
| Original Name | Substituted Name |
|---|---|
| Banana | Apple |
| Apple | Grapes |
| Grapes | Litchi |
| Litchi | Nuts |
| Nuts | Guava |
Revision Table: Word Substitution Questions
| Concept | Key Point | Example Application |
|---|---|---|
| Understanding Substitution | Identify what each original item is renamed to. | If 'red' is 'blue', then anything originally red is now called 'blue'. |
| Applying the Rule | Answer the question based on the new names, not the original ones. | Question: What is the color of blood? Answer: 'blue' (if 'red' is 'blue'). |
| Avoiding Confusion | Do not apply the substitution chain (e.g., red > blue > green). Only use the direct substitution for the item in question. | If 'red' is 'blue' and 'blue' is 'green', and the question is about 'red', the answer uses 'blue', not 'green'. |
Additional Information: Types of Logical Reasoning Puzzles
Logical reasoning includes various types of questions that test your analytical and critical thinking skills. Word substitution is just one type. Other common types include:
- Coding-Decoding: Letters, numbers, or words are coded according to a specific pattern.
- Blood Relations: Understanding family relationships.
- Direction Sense: Problems based on directions and distances.
- Series Completion: Finding the next term in a sequence of numbers, letters, or figures.
- Ranking and Ordering: Arranging people or items based on given conditions.
- Syllogism: Drawing conclusions from given statements.
Practicing these different types helps improve your logical reasoning abilities for competitive exams.
