If P ÷ Q – R + S – T × U, then which of the following statements is NOT correct?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. P is the mother-in-law of U.
In the diagram shown;
The square shows males, the circle shows females, vertical lines show generations, a single horizontal line shows brothers or sisters, and double lines show a couple.
From the above tree, P is not the mother-in-law of U.
Hence, P is the mother-in-law of U is the correct answer.
