Question (English)

In a certain code language,
$A + B$ means ‘A is the son of B’,
$A - B$ means ‘A is the sister of B’,
$A \times B$ means ‘A is the brother of B’ and
$A \div B$ means ‘A is the mother of B’.
Based on the above, how is T related to P if ‘$P \div Q \times R - M + T$’?

  1. Brother
  2. Husband ✓ Correct
  3. Father
  4. Son
Explanation:

Step-by-step decoding of the expression $P \div Q \times R - M + T$:

  • $P \div Q$: P is the mother of Q. (So, P is female)
  • $Q \times R$: Q is the brother of R. (So, Q is male and sibling of R)
  • $R - M$: R is the sister of M. (So, R is female and sibling of M)
  • $M + T$: M is the son of T. (So, M is male)

Conclusion:

  • Since P is the mother of Q, and Q, R, M are siblings (brothers/sisters), P is the mother of M as well.
  • The statement $M + T$ says M is the son of T.
  • Since M is the son of both P (mother) and T, T must be the father.
  • Therefore, T is the Husband of P.

प्रश्न (हिंदी)

एक निश्चित कूट भाषा में,
$A + B$ का अर्थ है ‘A, B का पुत्र है’,
$A - B$ का अर्थ है ‘A, B की बहन है’,
$A \times B$ का अर्थ है ‘A, B का भाई है’ और
$A \div B$ का अर्थ है ‘A, B की माता है’.
उपरोक्त के आधार पर, यदि ‘$P \div Q \times R - M + T$’ है, तो T, P से किस प्रकार संबंधित है?

  1. भाई (Brother)
  2. पति (Husband)
  3. पिता (Father)
  4. पुत्र (Son)
स्पष्टीकरण:

आइए समीकरण $P \div Q \times R - M + T$ को डिकोड करते हैं:

  1. $P \div Q$: P, Q की माता है। (P महिला है)
  2. $Q \times R$: Q, R का भाई है। (Q पुरुष है)
  3. $R - M$: R, M की बहन है।
  4. $M + T$: M, T का पुत्र है।

निष्कर्ष:

  • P, Q, R और M की माता है (चूंकि Q, R, M भाई-बहन हैं)।
  • M, T का पुत्र है। चूंकि P माता है, तो T अनिवार्य रूप से पिता होगा।
  • अतः, T, P का पति (Husband) है।
