$X-Z$ means X is the mother of Z ;

$X\times Z$ means X is the father of Z and
$X+Z$ means X is the daughter of Z.
Now, if $M-N\times T+Q$, then which of the following is not true?

• A. T is N's daughter
• B. N is the wife Q
• C. M is the mother-in-law of Q
• D. Q is the wife of N
• E. T is the granddaughter of M

Answer 1

The correct option is B N is the wife Q

M - N $\times$ T + Q means

M is the mother of N, who is the father of T, who is the daughter of Q i.e.

N and Q are husband and wife and their child is T.

M is the mother of N, and thus the grandmother of T.

So, option B is incorrect because Q is the wife of N.

option B.
