Question 171

# Is D the mother of S ? I. L is the husband of D. L has only three children.II.N is the brother of S and P. P is the daughter of L

Solution

Clearly, I alone and II alone are not sufficient since there is no data about S and D in I & II respectively.

I & II : L is the husband of D, => D is female and they have 3 children.

Since P is the daughter of L and N is the brother of S and P

$$\therefore$$ N, S and P are siblings and are children of L and D.

Thus, D is the mother of S.

Thus, I & II together are sufficient.
