'A + B' means 'A is the daughter of B',

'A - B' means 'A is the brother of B',

'A × B' means 'A is the wife of B' and

'A ÷ B' means 'A is the father of B'.

View answer & explanation

Correct answer

Answer: (c)C.

Niece

Why this answer is correct

Preparing the family tree diagram by using the following symbols:

 

Based on the expression 'C + V X R - N - M':

  1. C + V: C is the daughter of V.

  2. V X R: V is the wife of R (so R is the father of C).

  3. R - N: R is the brother of N.

  4. N - M: N is the brother of M.

Since R is the brother of M and C is the daughter of R, C is the niece of M.
