If 'P + Q' means P is the father of Q, 'P - Q' means P is the wife of Q, and 'P × Q' means P is the brother of Q, which of the following expressions shows that 'A is the maternal uncle of D'?

Question

Accepted Answer

Let's test each option logically based on the given definitions:
* '+' $ightarrow$ Father ($P$ is male, parent of $Q$)
* '-' $ightarrow$ Wife ($P$ is female, married to $Q$)
* '$	imes$' $ightarrow$ Brother ($P$ is male, sibling of $Q$)

We need **A as the maternal uncle of D**, meaning:
* $A$ must be male ($+$, $	imes$, or + relation).
* $A$ must be the brother of $D$'s mother.

Let's evaluate the options (testing typical correct expression patterns like **$A 	imes B + D$** or similar):
Let's check expression: **$A 	imes B + D$**
1. '$A 	imes B$': $A$ is the brother of $B$.
2. '$B + D$': $B$ is the father of $D$.
* *Result:* $A$ is the brother of $D$'s father $ightarrow$ Paternal Uncle.

Now, let's check if $D$'s mother is involved. For a maternal uncle, $A$ must be the brother of $D$'s mother ($E$).
Expression: **$A 	imes E - F + D$** (Too complex). Let's use direct options usually found in DDCET:
If expression is **$A 	imes B - C + D$** where $B$ is female, $C$ is male...
Let's test **$A 	imes B - C$**:
Let's verify: **$A$ is maternal uncle of $D$** requires $A$ to be brother of mother of $D$. If $D$'s mother is female $M$, and $A 	imes M$ (A is brother of M), and $M$ is mother of $D$ (usually represented via marriage/parenthood).

**Answer Format for DDCET Exams:** Look for the option where the male symbol/relation leads to a brother relationship connected to a female parent. (Typically, verify options by drawing a mini family tree for each choice during the exam). *Always check gender constraints first to eliminate options quickly.*
