This question was previously asked in
RRB ALP/Technician 2018 CBT 2 Electronics Mechanic Question Paper (23-Jan-2019) (Shift 1)
The correct answer is
X is the brother of Y

Symbol Decoding

First, let's understand the meaning of each symbol:

  • \(C\) D$ means C is the husband of D. (C is male)
  • \(C & D\) means C is the mother of D. (C is female)
  • \(C % D\) means C is the son of D. (C is male)

Expression Breakdown

Now, let's break down the expression \(X % Z\) W & Y$ step by step:

  • \(X % Z\): This means X is the son of Z. From this, we know X is male.
  • \(Z\) W$: This means Z is the husband of W. Therefore, Z is male and W is female. They are a couple.
  • \(W & Y\): This means W is the mother of Y.

Family Structure

Combining the information:

  • X is the son of Z.
  • Z is the husband of W. This implies Z and W are the parents of X.
  • W is the mother of Y. Since Z is W's husband, Z is also the father of Y.
  • Therefore, X and Y are siblings, children of parents Z and W.

Applying the Constraint

The problem states that W has only one son.

  • We know X is male (X is the son of Z).
  • Since X is a son of W, and W has only one son, X must be that unique son.
  • This means Y cannot be a son. Therefore, Y must be a daughter.

Final Relationship

We have established that:

  • X is male (brother).
  • Y is female (sister).
  • They are siblings.

Thus, X is the brother of Y.
