Question

The following question is based on the information given below.

1. 'P x Q' means 'P is the father of Q'
2. 'P - Q' means 'P is the sister of Q'.
3. 'P + Q' means 'P is the mother of Q'.
4. 'P +Q' means 'P is the brother of Q'
   

Which of the following represents 'J is the son of F'?

Options

• J ÷ R - T x F

• J + R - T x F

• J ÷ M - N x F

• None of the above

Answer 1

None of the above
Explanation:
From option, J ÷ R - T x F

From option, J + R - T x F

So, initially, it is proved that J is female since J is the mother of R. So, J cannot be the son of F because to be a son J must be male.
From option, J ÷ M - N x F

Hence, none of the options shows that J is the son of F.
