Question

In a certain code language,

'A + B' means 'A is the mother of B',

'A - B' means 'A is the daughter of B',

'A x B' means 'A is the son of B' and

'A÷ B' means 'A is the brother of B'.

How is F related to C if 'C -D ÷ E x F + G'?

• A. Mother's father
• B. Father's mother
• C. Daughter's son
• D. Father's brother

Answer 1

Answer:

B. Father's mother

Given meanings:

• A + B → A is the mother of B

• A − B → A is the daughter of B

• A × B → A is the son of B

• A ÷ B → A is the brother of B

C − D ÷ E × F + G

C − D

C is the daughter of D
→ D is the parent of C

D ÷ E

D is the brother of E
→ D and E have the same parents

E × F

E is the son of F
→ F is the parent of E
Since D is E’s brother, F is also the parent of D

F + G

F is the mother of G
→ Confirms F is female

Now determine the relation between F and C:

• F is the mother of D

• D is the parent of C

So, F is the grandmother of C.
