1. If 'A X B' means 'A is the Daughter of B'. 'A + B' means 'A is the husband of B' and 'A - B' means ' A is the sister of B', then what does ' M + N - P X Q' Mean?

Sol : 

M + N - P X Q  => M is the Husband of N, N is the sister of P and P is the Daughter of Q.

N and P are sisters and the daughters of Q. Q is either mother or father of N and P. so M is Son-In-Law to Q.

Have a look at the below image for more clarifications.

Directions (2-3): Study the following information carefully and answer the questions given below.

    ' P X Q' means 'P is Sister of Q'

    ' P + Q' means 'P is mother of Q'

    'P - Q' means 'P is father of Q'

    'P % Q' means 'P is brother of Q'

2. Which of the following represents 'A is nephew of B'?

1.     A % B - C
2.     C % B - A
3.     C X B + A X D
4.     C % B - A % D
5.     None of the Above

Sol : 

A is nephew of B means, A must be MALE. The symbols '-' and '%' indicate the male Gender. So, A must be followed by either '-' or '%'. So, checking of options 1 and 4 will be enough to solve this question. 

    1. A % B - C  => A is brother of B and B is father of C. Here, A is C's paternal Uncle. 

    4. C % B - A % D  => C is brother of B, B is father of A and A is brother of D. So here, A is son of B.

So the answer is, 5. None of the Above 

3. Which of the following represents 'W is Grand Father of H'??

1. W + T - H
2. W % T - H

   3. W % T + H  => W is brother of T and T is mother of H. W is maternal uncle of H.

Blood Relation-Set 2

POINTS TO REMEMBER : 

• If the question is "How is A related to B". Then you must know the gender of A to answer the question
• Without knowing A's gender, you cannot determine the relation from A to B
• If a person is Uncle or Aunt to "A", A is that person's nephew (if A is Male) or niece (if A is female)
• Cousin is a common Gender (I mean, you can use this word for both Male and Female)
• Ex : A says to B, "you are the son of my grand father's only son".
• How is B related to A?
• How is A related to B?
• Ans : 
• B is Brother of A.
• My grand father's only son = A's father (grand father's only son means only ONE son.. No other son and no daughter also)
• A is either brother or sister to B
• A and B are siblings. B is brother to A as we know the Gender of B. But we dont know the Gender of A. So we cant say whether A is Brother or Sister to B.
