The symbol table is as follows:

According to the question:

P @ Q → P is the husband of Q.

J # L → L is the son of J

N $ M → N is the brother of M

Options:

1) A # B $ C @ D → B is the son of A and brother of C who is the husband of D. 

Thus, A is one of the parents of B.

2) C $ D @ A # B → C is the brother of D who is the husband of A. B is the son of A. 

Thus, A is the mother of B.

3) B $ C # A @ D → B is the brother of C. A is the son of C. A is the husband of D. 

Thus, B is the uncle of A.

4) D @ B # C $ A → D is the husband of B. C is the son of B and brother of A. 

Thus, B is the mother of A.

Hence, "option (4)" ensures that A's mother is B.

Let us first decode the given symbols and then draw a family tree.

‘F 4 I 6 R 4 S 6 T 5 S’ means F is mother of I, I is sister of R, R is mother of S, S is sister of T, T is brother of S.

Now draw family tree using following notations

Hence, S is granddaughter of F.

Preparing the family tree by using the following symbol:

Here, we make a table for the given relation:

The family tree diagram of 'H # K # U + T @ M % G + N' is →

H is father of K, K is father of U, U is Sister of T, T is son of M, M is Daughter of G, G is Sister of N.

Here, G is the Maternal grandmother of U as per the diagram.

Hence, the correct answer is "Maternal grandmother".

Let's check options one by one:

Option 1) X ⊗ Z ⊕ Y  

Option 2)  Y ⊘ Z ⊕ X  

Option 3) X ⊘ Z ⊙ U ⊕ Y  

Option 4) Y ⊘ Z ⊙ X

1) N % R * M → N is father of R, R is sister of M

2) N * M % S # R → N is sister of M, M is father of S, S is mother of R

3) N * M % R → N is sister of M, M is father of R

4) R * M # N → R is sister of M, M is mother of N

Hence, ‘3’ is the correct answer.

The logic followed here is : (2nd number × 5) - 1st number = 3rd number

Given :

• First row : 18, 9, 27

​(9 × 5) - 18 = 27

45 - 18 = 27

27 = 27 (LHS = RHS)

​And,

• Second row : 40, 36, 140

(36 × 5) - 40 = 140

180 - 40 = 140

140 = 140 (LHS = RHS)

Similarly,

• Third row : 40, 13, ?

​(13 × 5) - 40 = ?

65 - 40 = ?

25 = ?

Hence, "25" is the correct answer.

A + B - C ÷ D × E - F → A is sister of B, B is brother of C, C is wife of D, D is father of E, E is brother of F.

By using the symbols in the table given below, we can draw the following family tree:

1. C is the mother of F → True

2. E is the brother of B → False (E is son of D)

3. A is the sister of the wife of D → True

4. A is the sister of C → True

Hence, ‘E is the brother of B’ is the correct answer.

Family Chart:

Decoding the Symbols:

Given: A @ B # C + D + E

It means: B is Brother of A, C is Sister of B, D is Father of C, E is Father of D.

Here, E is the 'Father’s Father' of A.

Hence, the correct answer is "Option 3".

Given :

So,

• Option - (1) : B ÷ A + C → B is the father of A who is the mother of C.

​

Here, A is the mother of C.

• Option - (2) : A - B ÷ C → A is the sister of B who is the father of C.

​

Here, A is the paternal aunt of C.

• Option - (3) : A + B ÷ C → A is the mother of B who is the father of C.

​

Here, A is the paternal grandmother of C.

• Option - (4) : A ÷ B + C → A is the father of B who is the mother of C.

​

Here, A is the maternal grandfather of C.

Hence, "Option - (4)" is the correct answer.

The logic followed here is : (5 × 1st number) - (4 × 2nd number) = 3rd number

So,

• First row - 12, 7, 32

(5 × 12) - (4 × 7) = 32

60 - 28 = 32

32 = 32 (LHS = RHS)

And, 

• Second row - 17, 13, 33

(5 × 17) - (4 × 13) = 33

85 - 52 = 33

33 = 33 (LHS = RHS)

Similarly,

• Third row - 14, 8, ?

(5 × 14) - (4 × 8) = ?

70 - 32 = ?

38 = ? 

Hence, "38" is the correct answer.

Family Chart:

Given:

‘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’.

Let us first decode the given symbols and then draw a family tree.

Now break the code ‘T × V + Z’

1) T × V

‘T × V’ means ‘T is the brother of V’.

2) V + Z

‘V + Z’ means ‘V is the daughter of Z’.

Now, check all the options

Option (1) T is the uncle of Z → False (T is the son of Z)

Option (2) T is the father of Z → False (T is the son of Z)

Option (3) T is the son of Z → True

Option (4) T is the brother of Z → False (T is the son of Z and brother of V)

Hence, “option (3)” is the correct answer.

Given :

Statements given : G % V @ K & P and G # S % M

Explanation :

• G % V → G is the sister of V.

​

• V @ K → V is the husband of K.

​

• K & P → K is the mother of P.

​

• G # S → G is the daughter of S.

​

• S % M → S is the sister of M.

​

Thus, from the final family tree S is the paternal grandmother i.e father's mother of P.

Hence, "Father’s mother" is the correct answer.

Preparing the family tree using the following symbols:

According to the given question: 

'P $ Q # V @ B' is shown as a family tree diagram below,

Clearly, P is the Husband's brother to B

Hence, "Option 4" is the correct answer.

Family Chart:

Given:

Now we substitute the values in the given equation:

A & B # C & D @ E % F + G becomes A is the wife of B, B is the father of C, C is the wife of D, D is the son E, E is the husband of F, F is the mother of G.       

From the chart we can see that, A is mother-in-law of D.

Hence, the correct answer is "Option 2".

Family Table:

Let us first decode the given symbols and then draw a family tree.

Drawing the Family tree for 'J ÷ H + M ÷ S - F'

So, F is the Grandmother of J.

Hence, the correct answer is "Grandmother".
