Mother's father

Blood Relation Logic Explained

This question requires decoding a series of relationships based on given codes. We need to determine the specific relationship between P and T by analyzing the expression 'P + Q – R × S ÷ T'.

Understanding the Relationship Codes

The provided codes define the relationships as follows:

  • $+$ denotes 'Husband'
  • $-$ denotes 'Mother'
  • $×$ denotes 'Wife'
  • $÷$ denotes 'Father'

Decoding the Expression Step-by-Step

Analyzing 'P + Q – R'

  1. P + Q: This means 'P is the husband of Q'. From this, we know P is male.
  2. Q - R: This means 'Q is the mother of R'. We know Q is female.
  3. Conclusion for P, Q, R: Since P is the husband of Q, and Q is the mother of R, P is the father of R.

Analyzing 'R × S ÷ T'

  1. R × S: This means 'R is the wife of S'. This confirms R is female.
  2. S ÷ T: This means 'S is the father of T'. We know S is male.
  3. Conclusion for R, S, T: Since R is the wife of S, and S is the father of T, R must be the mother of T.

Determining the Final Relationship: P to T

Synthesizing the information derived:

  • From the first part, P is the father of R.
  • From the second part, R is the mother of T.

Therefore, P is the father of T's mother.

The father of one's mother is their maternal grandfather.

Hence, P is the maternal grandfather of T.
