Coded Blood Relation Problems MCQ Quiz - Objective Question with Answer for Coded Blood Relation Problems - Download Free PDF

Given:

K + L means K is the son of L;

K - L means K is the sister of L;

K % L means K is the brother of L

K x L means K is the mother of L,

1. D - B + C – A → D is sister of B, B is son of C and C is sister of A.

As, C is sister of A and D is daughter of C, it means D is the niece of A.

2. D + B - C % A → D is son of B, B is sister of C, C is brother of A

As, D is son of B and B, C and C are siblings, D is nephew of A.

Or, D is male and to be niece of A, D must be female, so clearly this option cannot be the answer.

3. D × B - C + A → D is mother of B, B is sister of C, C is son of A

As, D is mother of B and B is sister of C, who is son of A, here D is wife of A.

4. D + B × C – A → D is son of B, B is mother of C, C is sister of A

As, D is son of B and B is mother of C, who is sister of A, here B is mother of A, D and C which means A and D are siblings.

Or, D is male and to be niece of A, D must be female, so clearly this option cannot be the answer.

Hence, ‘D - B + C – A’ shows that D is the niece of A.

Preparing the family tree using the following symbol:

According to the given information,

Let's check each option one by one;

1) P # Q @ R * S → False

2) P @ Q # R $ S → True

So, S is the brother-in-law of P.

3) P * Q $ R # S → False

4) P $ Q @ R $ S → False

Hence, option (2) is the correct answer.

Decoding symbols:

Given: P x Q ÷ R – S + T

P x Q → P is the brother of Q.

Q ÷ R → Q is the wife of R.

R – S → R is the father of S.

S + T → S is the sister of T.

Thus, P is T's mother’s brother or maternal uncle.

Hence, the correct answer is "Option 2"

Family Chart:

Given Expression: H - I × J ÷ K + G

It Implies: H is wife of I, I is son of J, J is husband of K, K is daughter of G.

So, I is daughter's son of G.

Hence, the correct answer is 'Option 1'.

Given: 

By checking option 1) N / P $ M & Q

Here, we can see that M is daughter of N.

Hence, N / P $ M & Q is 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)

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:

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".

The above given information can be shown using family tree using following symbols:

and,

Family tree,

Hence, "T is the daughter ­in ­law of R" will be true for P = Q > R -­ S + T.
