A is the father of B. C and D are brothers of B. E is the wife of D and F is the daughter of E. How is E related to A? MCQ with Answer and Explanation

Explanation:
P ÷ Q → P mother of Q. Q – S → Q father of S. S + K → S brother of K, so K is also son of Q. K – T → K father of T. T × R → T husband of R. K is father-in-law of R (true). S is brother of K, T's father (true). Q is father of K, so father of T's father (true). P is mother of Q, so P is grandmother of K, not mother of K's mother. Hence C is incorrect.

Explanation:
"My wife's mother-in-law" is Manoj's mother. So, the girl's grandfather's wife (grandmother) is Manoj's mother. Since Manoj has no siblings, he must be the father of that girl.

Explanation:
I is the wife of J. J is the son of K. K is the husband of L. Hence, I is the wife of L's son, i.e., L's daughter-in-law. The printed options appear to contain an error.
