A + B means 'A is mother of B' A - B means 'A is husband of B' A × B…

The correct answer is Option (1) → Brother

To find the relationship between K and J, we need to break down the expression $Q \div U \times K \times H - D + J$ step by step to build a family tree.

1. Decoding the Expression

• $Q \div U$: $Q$ is the brother of $U$.
• $U \times K$: $U$ is the son of $K$. (This means $Q$ is also the son of $K$).
• $K \times H$: $K$ is the son of $H$.
• $H - D$: $H$ is the husband of $D$. (This means $D$ is the wife of $H$).
• $D + J$: $D$ is the mother of $J$.

2. Building the Family Tree

• Generation 1 (Top): $H$ (Male) and $D$ (Female) are a married couple.
• Generation 2 (Middle): They have children. We know $K$ is the son of $H$ and $D$. We also know $D$ is the mother of $J$. Therefore, $K$ and $J$ are siblings.
• Generation 3 (Bottom): $K$ has sons $Q$ and $U$.

3. Determining the Relation

We have established that $K$ and $J$ are children of the same parents ($H$ and $D$).

• From the expression $K \times H$, we know $K$ is a son, so $K$ is male.
• Since $K$ is the male sibling of $J$, $K$ is the brother of $J$.
