45-48 are based on the followinginformation :

A + B means A is son of B.

A – B means A is wife of B.

A $$\times$$​ B means A is brother of B.

A ÷ B means A is mother of B.

A = B means A is sister of B.

What does J = K ÷ L mean ? 

Correct option is A

​

• J = K means J is the sister of K.
• K ÷ L means K is the mother of L.

Since K is L's mother, L is K’s child. And since J is K’s sister, J would be L’s aunt.

So the correct answer is (A) J is Aunt of L.
