Question

If A + B means A is the sister of B; A x B means A is the wife of B, A % B means A is the father of B, and A - B means A is the brother of B, then which of the following means T is the daughter of P? 
 

• A. P x Q % R + S - T
• B. P x Q % R + T - S
• C. P x Q % R + T + S
• D. P x Q % R - T + S
• E. P x Q % R + S + T

Hint:

Work through the expression step by step, tracking gender and relationships.

Answer 1

The Correct Option is D

Step 1: Decoding Symbols:
A + B: A is sister of B
A x B: A is wife of B
A % B: A is father of B
A - B: A is brother of B
We need: T is daughter of P. Daughter means P is parent of T and T is female.

Step 2: Analyzing Option (D):
P x Q % R - T + S
Step-by-step:
P x Q → P is wife of Q. So P is female, Q is male.
Q % R → Q is father of R. So R is child of Q and P (since P is wife of Q).
R - T → R is brother of T. So R and T are siblings, both children of Q and P. T is sibling of R.
T + S → T is sister of S. So T is female.
Thus, T is daughter of P (since P is mother).

Step 3: Verification:
The expression correctly establishes T as daughter of P.
