A # B means ‘A is the husband of B’. A & B means ‘A is the daughter of B’. A @ B means ‘A is the grandmother of B’. A % B means ‘A is the son of B’. If E @ F % G # H & I @ J, then how is G related to J if I has only one child?

Understanding the Blood Relation Coded Symbols
This question involves decoding a relationship expression given in coded form. We need to understand what each symbol represents to build the family tree and find the relationship between G and J.
Let's look at the meaning of each symbol provided:
- A # B means ‘A is the husband of B’
- A & B means ‘A is the daughter of B’
- A @ B means ‘A is the grandmother of B’
- A % B means ‘A is the son of B’
Analyzing the Given Expression: E @ F % G # H & I @ J
Now, let's break down the given expression step-by-step:
- E @ F: E is the grandmother of F. This means E is a female and is a parent of F's parent.
- F % G: F is the son of G. This means F is a male and G is a parent of F.
- G # H: G is the husband of H. This means G is a male and H is a female, and they are married.
- H & I: H is the daughter of I. This means H is a female and I is a parent of H.
- I @ J: I is the grandmother of J. This means I is a female and is a parent of J's parent.
Building the Family Tree Based on Relations
Let's combine these relationships to see how the individuals are connected:
- From G # H, we know G and H are married, with G being the husband and H the wife.
- From F % G, F is the son of G. Since G is married to H, F is also the son of H. So, F is the child of G and H.
- From H & I, H is the daughter of I. This means I is the parent of H.
- From I @ J, I is the grandmother of J. Since H is I's daughter, I is the mother of H (as I is female from I @ J and H is her daughter).
- I is the grandmother of J. This means J is the child of I's child. I's only child we know from the relations is H. Therefore, J must be the child of H.
So far, we have:
- G and H are a couple (G is husband, H is wife).
- F is their son.
- H is the daughter of I.
- I is the mother of H and grandmother of J.
- J is the child of H.
Incorporating the Condition: I has only one child
The question states that I has only one child. We deduced that H is a daughter of I. Since H is the only child of I, H is I's only offspring.
We also know I is the grandmother of J. A grandmother is a parent of one's parent. Since H is I's only child, J must be the child of H. This confirms our previous deduction.
Determining the Relationship between G and J
We have established that:
- G is the husband of H.
- J is the child of H.
Since G is the husband of H, and J is the child of H, J is also the child of G. Therefore, G is the father of J.
Final Conclusion
Based on the decoding of the symbols, the given expression, and the condition that I has only one child, we have determined that G is the father of J.
| Relation | Inference |
|---|---|
| G # H | G is husband of H (G: Male, H: Female) |
| F % G | F is son of G (F: Male, G: Parent of F) |
| H & I | H is daughter of I (H: Female, I: Parent of H) |
| I @ J | I is grandmother of J (I: Female, Parent of J's parent) |
| Combining F%G & G#H | F is son of G and H |
| Combining H&I & I@J | H is I's daughter; I is grandmother of J. Implies J is child of I's child. |
| Condition: I has only one child + H & I | H is the only child of I. |
| Combining I@J & I's only child is H | J must be the child of H. |
| Combining G#H & J is child of H | G is husband of H, J is child of H. Therefore, J is child of G. |
| Final Relation | G is the father of J. |

Additional Information: Solving Blood Relation Puzzles
Blood relation puzzles test your ability to understand and deduce relationships between individuals based on given information. When solving coded blood relation questions:
- Always decode the symbols first and write down what each one means clearly.
- Break down the complex expression into smaller, manageable relationship pairs.
- Try to build a simple family tree or diagram as you go, showing the connections between individuals.
- Pay close attention to gender indications. Symbols like 'husband', 'daughter', 'son', 'grandmother' clearly define gender.
- Note down any extra conditions given, like "only child", "no son", etc., as these are crucial for narrowing down possibilities.
- Combine the smaller relations to find the overall relationship between the people asked in the question.
Important Questions from Coded Blood Relation Problems
‘R+S’ means ‘R is the daughter of S’. ‘R−S’ means ‘R is the husband of S’.‘R × S’ means ‘R is the brother of S’. If ‘T × V + Z’, then which of the following options is true?
'P × Q' means 'P is the wife of Q'. 'P + Q' means 'P is the father of Q'. 'P ÷ Q' means 'P is the daughter of Q'. 'P - Q' means 'P is the son of Q'. How is E related to I in the expression 'E ÷ F + G - H ÷ I' ?
'K % L' means 'K is the brother of L', 'K $ L' means 'K is the husband of L', 'K @ L' means 'K is the sister of L', 'K # L' means 'K is the mother of L'.
How is H related to M in the expression ‘X @ P % T # M $ Y # J @ H’?
If ‘A % B’ means ‘A is the father of B’, ‘A # B’ means ‘A is the brother of B’, and ‘A $ B’ means ‘A is the wife of B’, then how is K related to R in the given expression?
K $ H % Y # M # R
If 'A + B' means 'A is the daughter of B ', 'A × B' means 'A is the sister of B', and 'A = B' means 'A is the wife of B', then how is G related to R in the expression 'C × G × U + M = R'?
