1 answers
- B and D are sisters of M. ⇒ from statement I: B, D and M are siblings where B and D are females.
- M’s father T is husband of P. ⇒ from statement II: T is father of M. P is wife of T and P is mother of M.
- Out of the three children of T, only one is a boy. ⇒ from statement III: T has only one son.
On combining, I and II statement:
B,D and M are siblings (where B and D are females); T and P are M’s parents where T is father and P is mother.
⇒ T is father, P is mother. Their kids are B (daughter), D (daughter) and M (gender unknown)
We can’t find the answer with this information.
On combining I and III statement
B, D and M are siblings (where B and D are females); T has only one son.
We cannot find the answer with this information because relation of P is not defined.
On combining statement II and III:
T is father of M and P is mother of M; Out of the three children of T, only one is a boy.
This means T has only 1 boy child and 2 girl children. Since P is wife of T, P has 2 daughters.
Hence, only statement II and III are required to answer the question.
