Question

Suppose A+B means 'A is the daughter of B' A÷B means 'A is the mother of B' AxB means 'A is the son of B' A-B means 'A is the father of B' If P+Q-RXS÷T, then how is P related to T?

• A. P is the wife of T
• B. P is the sister of T
• C. T is the grandmother of P
• D. T is the mother of P

Answer 1

Answer:

B. P is the sister of T

P is the sister of T.

Here is the step-by-step breakdown of the expression P + Q - R × S ÷ T:

1. Break Down the Relationships

• P + Q: P is the daughter of Q.

• Q - R: Q is the father of R.

  • Meaning so far: P and R are siblings (children of Q). Since P is a daughter, P is R's sister.

• R × S: R is the son of S.

  • Meaning so far: Since Q is R's father, S must be R's mother (Q and S are married). Consequently, S is also the mother of P.

• S ÷ T: S is the mother of T.

  • Meaning so far: P, R, and T all share the same mother (S) and father (Q). They are all siblings.

2. Determine P's Relation to T

• P, R, and T are all brothers and sisters in the same family.

• Since the first clue establishes that P is a daughter (female), P is the sister of T.
