The question given below consists of two statements I and II. You have to decide whether the data given in the statements are sufficient to answer the question given below. Read both the statements and choose the correct option. Who is the brother-in-law of N? I. N is B's mother and is married to A's brother. II. M and D are A's brothers and L is D's wife. Correct Answer The data in statements I and II together are sufficient to answer the question.

The symbol and its meaning are as follows:

I. N is B's mother and is married to A's brother.

No mention of N here, so can't decide who is N's brother-in-law.

Combining I and II 

A has 2 brothers M and D. D married to L thus the other brother M must be married to N. Therefore at least 1 brother-in-law of N is D.

Hence, The data in statements I and II together are sufficient to answer the question
