Verbal Reasoning - Blood Relation Test - Discussion

Each of these questions is based on the following information:

  1. A + B means A is the mother of B.
  2. A - B means A is the sister of B.
  3. A * B means A is the father of B.
  4. A β B means A is the brother of B.

2. 

Which of the following means that N is the maternal uncle of M?

[A]. N β P - L + E - M
[B]. N - Y + A β M
[C]. M - Y * P - N
[D]. N β C + F * M

Answer: Option A

Explanation:

N β P → N is the brother of P

P - L → P is the sister of L

L + E → L is the mother of E

E - M → E is the sister of M.

Hence, L is the mother of M, P is the maternal aunt of M and N is the maternal uncle of M.

You can simplify this answer. You don't need E and P.

M and E are siblings so they have only one mother (L) and so if you don't mention E, it right.

N, P and L are siblings so even if you don't mention P, you are not going to change the relation between N and L.

ANSWER : N is the brother of L and M is L's child.

N β L + M.
