‘P + F’ means ‘P is the son of F’
‘P – F’ means ‘P is the wife of F’
‘P × F’ means ‘P is the brother of F’
‘P ÷ F’ means ‘P is the mother of F’
‘P = F’ means ‘P is the sister of F’.
What does ‘K = R ÷ M’ mean?
Correct Answer :
K is the aunt (mother’s sister) of M
Solution :
The correct answer is: K is the aunt (mother’s sister) of M.
To determine the relation represented by the expression ‘K = R ÷ M’, let us break down the given symbolic relations step-by-step:
1. ‘P = F’ means ‘P is the sister of F’. Therefore, ‘K = R’ means that K is the sister of R.
2. ‘P ÷ F’ means ‘P is the mother of F’. Therefore, ‘R ÷ M’ means that R is the mother of M.
Combining these two steps:
- R is the mother of M.
- K is the sister of R.
Since K is the sister of M's mother (R), K is the mother's sister (aunt) of M.
Hence, ‘K = R ÷ M’ means K is the aunt (mother’s sister) of M.
