Question

Read the following information carefully to choose the best option for the question:

‘P + Q’ means that ‘P is the son of Q’,
‘P × Q’ means that ‘P is the husband of Q’,
‘P – Q’ means that ‘P is the brother of Q’.

Which of the following means ‘A is the son-in-law of G’?

• A. A × U + S × G
• B. A + S
• C. A – S + U × G
• D. A × U

Answer 1

The Correct Option is A

1. We need to find an expression that denotes 'A is the son-in-law of G'.
2. Understanding the symbols:
   • 'P + Q' means 'P is the son of Q'.
   • 'P × Q' means 'P is the husband of Q'.
   • 'P – Q' means 'P is the brother of Q'.
3. Analysis of the given options:
   • Option 1: A × U + S × G
     • 'A × U' implies 'A is the husband of U'.
     • 'U + S' implies 'U is the son of S'.
     • 'S × G' implies 'S is the husband of G'.
     • Thus, 'A × U + S × G' means 'A is the son-in-law of G', because A is married to U (who is the child of S, and S is the spouse of G).
   • Option 2: A + S
     • 'A + S' means 'A is the son of S'.
   • Option 3: A – S + U × G
     • 'A – S' means 'A is the brother of S'.
     • 'U × G' means 'U is the husband of G'.
     • This does not relate A to G directly as a son-in-law.
   • Option 4: A × U
     • 'A × U' means 'A is the husband of U'.
     • There is no information about G, thus it cannot imply A is the son-in-law of G.
4. Therefore, the expression that correctly represents 'A is the son-in-law of G' is A × U + S × G.
