Question

$X+Y$ means $X$ is the sister of $Y.$
$X-Y$ means $X$ is the mother of $Y.$
$X\times Y$ means $X$ is the brother of $Y.$
$X÷Y$ means $X$ is the father of $Y.$
If $N-A÷B+D,$ then how is $D$ related to $N$?

• A. Grandson
• B. Nephew
• C. Granddaughter
• D. Can not be determined

Answer 1

The correct option is D Can not be determined

$N-A÷B+D$ means $N$ is the mother of $A,$ who is the father of $B,$ who is the sister of $D.$
Thus, $D$ is the son or daughter of $A$ and $N$ is the mother of $A.$
So, $D$ is either grandson or granddaughter of $N.$
