In a certain code language,

‘A+ B’ means ‘A is the mother of B’

‘A – B’ means ‘A is the husband of B’

‘A x B’ means ‘B is the sister of A’

‘A ÷ B’ means ‘A is the father of B’

Based on the above, how is B related to E if ‘D ÷ E – C + A x B ’?

To find how B is related to E in the expression ‘D ÷ E – C + A x B’, let us break down the relationships step-by-step from left to right:

1. D ÷ E: The operator ‘÷’ means the first person is the father of the second person. Therefore, D is the father of E.

2. E – C: The operator ‘–’ means the first person is the husband of the second. Therefore, E is the husband of C. This implies that E is male and C is female, and they are a married couple.

3. C + A: The operator ‘+’ means the first person is the mother of the second person. Therefore, C is the mother of A. Since E is married to C, E must be the father of A.

4. A x B: The operator ‘x’ means the second person is the sister of the first person. Therefore, B is the sister of A. This tells us that B is female (sister) and shares the same parents as A.

Since C and E are the parents of A, and B is the sister of A, B is also the child of C and E. Since B is female, B is the daughter of E.
