If A + B means A is the father of B, and A - B means A is the wife of B, then what does P + Q - R mean?
Correct answer: A. P is the father of Q and Q is the wife of R
- A. P is the father of Q and Q is the wife of R
- B. P is the wife of R
- C. R is the father of Q
- D. P and R are siblings
Explanation
The symbols are applied in order from left to right, so P plus Q gives the first relationship and Q minus R the second. Coded relation questions simply require substituting the definitions carefully. Inventing extra links beyond the symbols given is the usual error.
