In each question there are two statements: A and B.
Choose 1 if the question can be answered by one of the statements alone but not by the other.
Choose 2 if the question can be answered by using either statement alone.
Choose 3 if the question can be answered by using both the statements together but cannot be answered using either statement alone.
Choose 4 if the question cannot be answered even by using both the statements A and B.
F and M are father and mother of S, respectively. S has four uncles and three aunts. F has two siblings. The siblings of F and M are unmarried. How many brothers does M have?
A. F has two brothers.
B. M has five siblings.
Answer: Option A
F and M have a total of four brothers and three sisters.
Statement A states that F has two brothers, which means M should have two brothers.
∴ Statement A is alone sufficient.
Statement B is redundant as no additional information is provided.
Hence, option 1.
In a family gathering there are two males who are grandfathers and four males who are fathers. In the same gathering there are two females who are grandmothers and four females who are mothers. There is at least one grandson or a granddaughter present in this gathering. There are two husband-wife pairs in this group. These can either be a grandfather and a grandmother, or a father and a mother. The single grandfather (who wife is not present) has two grandsons and a son present. The single grandmother (whose husband is not present) has two granddaughters and a daughter present. A grandfather or a grandmother present with their spouses does not have any grandson or granddaughter present. What is the minimum number of people present in this gathering?
Answer: Option B
Here "-" represents the Husband-Wife pair.
∵ We want the minimum number of people, let us assume that the two grandfathers and two grandmothers have already been counted as fathers and mothers respectively.
∴ We have 4 fathers, 4 mothers, 2 grandsons and 2 granddaughters.
∴ Minimum number of people present = 4 + 4 + 2 + 2 = 12
Hence, option 2.
