Question:
If ‘A + B’ means ‘A is the son of B’, ‘A – B’ means ‘A is the daughter of B’, and ‘A * B’ means ‘A is the father of B’, which expression means ‘P is the maternal grandfather of S’?
यदि ‘A + B’ का अर्थ है ‘A, B का पुत्र है’, ‘A – B’ का अर्थ है ‘A, B की पुत्री है’, और ‘A * B’ का अर्थ है ‘A, B का पिता है’, तो किस अभिव्यक्ति का अर्थ है ‘P, S का नाना है’?
Options:
- \(P * Q – S\)
- \(P + Q * S\)
- \(P * Q + S\)
- \(P – Q * S\)
- \(P * Q – S\)
- \(P + Q * S\)
- \(P * Q + S\)
- \(P – Q * S\)
Correct Answer: a)
Explanation:
\(P * Q\) means P is the father of Q. \(Q – S\) means S is the daughter of Q (wait, S is daughter of Q means Q is mother of S). Thus, P is the father of Q, and Q is the mother of S, making P the maternal grandfather of S.
\(P * Q\) का अर्थ P, Q का पिता है। \(Q – S\) में Q, S की माता है, अतः P, S का नाना है।
