Understanding Coded Blood Relations Reasoning
This question involves understanding relationships expressed through codes. We are given specific meanings for the symbols '@' and '$' and need to find which coded expression translates to a particular family relationship.
Let's break down the given information:
- 'A @ B' means 'A is the son of B'.
- 'A $ B' means 'A is the sister of B'.
The target relationship we need to find is 'M is K's sister's son'. This means there is someone who is K's sister, and M is the son of that person. Let's represent K's sister as 'G' (since 'G' appears in the options). So, the target relationship is:
- G is the sister of K.
- M is the son of G.
Analyzing the Options for M is K's Sister's Son
We will examine each option to see which one represents the target relationship: 'M is the son of K's sister'.
Option 1: G @ K $ M Analysis
Let's decode this expression step by step from left to right:
- G @ K: G is the son of K.
- K $ M: K is the sister of M.
Combining these, we know G is K's son, and K is M's sister. This means M is K's sibling (either brother or sister, we don't know M's gender), and G is the son of that sibling. This does not mean M is K's sister's son. In fact, G is the son here, not M.
Option 2: K @ G $ M Analysis
Let's decode this expression step by step:
- K @ G: K is the son of G.
- G $ M: G is the sister of M.
Combining these, we know K is G's son, and G is M's sister. This means K is the son of M's sister. We are looking for M to be someone's son. This option describes K as the son, not M.
Option 3: M @ G $ K Analysis
Let's decode this expression step by step:
- M @ G: M is the son of G.
- G $ K: G is the sister of K.
Combining these, we know M is the son of G, and G is the sister of K. This means M is the son of K's sister (where G is K's sister). This exactly matches the target relationship: 'M is K's sister's son'.
Option 4: M $ G @ K Analysis
Let's decode this expression step by step:
- M $ G: M is the sister of G.
- G @ K: G is the son of K.
Combining these, we know M is G's sister, and G is K's son. This means M is the sister of K's son. We are looking for M to be a son, not a sister. This option does not match the target relationship.
Why Option 3 is the Correct Expression
Based on the analysis, the expression 'M @ G $ K' correctly translates to 'M is the son of G, and G is the sister of K'. Therefore, M is the son of K's sister. This directly matches the desired relationship.
| Code | Relationship Meaning |
|---|---|
| @ | is the son of |
| $ | is the sister of |

| 2 | K @ G $ M | K is son of G; G is sister of M | No |
| 3 | M @ G $ K | M is son of G; G is sister of K | Yes |
| 4 | M $ G @ K | M is sister of G; G is son of K | No |
Additional Information on Blood Relations Reasoning
Blood relations questions test your ability to understand family relationships and follow instructions given through codes or direct statements. These questions often appear in reasoning sections of competitive exams.
Tips for solving blood relations questions:
- Carefully note down the meaning of each symbol or code provided.
- Break down the target relationship into smaller steps.
- For coded relations, decode each segment of the expression from left to right.
- Visualize or draw a simple family tree if needed, but be cautious with coded relations as genders and connections might not be immediately clear for all individuals.
- Substitute the decoded relationships back into the target question to verify.
- Pay close attention to the gender implied by the relationship (e.g., 'son' implies male, 'sister' implies female, 'child' is gender-neutral).
Understanding basic family terms like paternal, maternal, sibling, cousin, nephew, niece, uncle, aunt is crucial for these problems.
