In a small town lived a close-knit family where every relation could be expressed through simple symbols. For instance, when they said A × B, it meant A is the father of B, while A ÷ B meant A is the mother of B. The younger ones were often introduced with A + B, meaning A was the daughter of B, and the bond of brotherhood was shown by A - B (A is brother of B). One day, the children in the family turned these symbols into a playful code. Instead of introducing their parents and siblings in words, they spoke only in symbols. ”Look,” giggled little Meena, ”M + N ÷ O!” Everyone laughed, because they knew it meant Meena was the daughter of N, and N was the mother of O, making her O’s sister. What started as a code soon became a family game, making the bonds of father, mother, daughter, and brother not just relations, but symbols of love and togetherness. (165 words)
Which of the following means that R is wife of P?
Correct Answer :
P × T – Q + R
Solution :
Correct Answer: P × T – Q + R
Let us analyze the given symbols and their meanings to find which expression implies that R is the wife of P.
Symbol Codes Given:
1. A × B means A is the father of B.
2. A ÷ B means A is the mother of B.
3. A + B means A is the daughter of B.
4. A - B means A is the brother of B.
Now, let us evaluate the expression: P × T – Q + R step-by-step from left to right:
1. P × T: P is the father of T. (This implies P is male).
2. T – Q: T is the brother of Q. Since T is the brother of Q and P is T's father, P is also the father of Q.
3. Q + R: Q is the daughter of R. (This implies R is a parent of Q).
Since P is the father of Q, and Q is also the daughter of R, R must be the mother of Q. Therefore, P (father) and R (mother) are married, which means R is the wife of P.
Thus, the correct expression is P × T – Q + R.
