I. Mr. Jagdish has six sons and each has one sister.

II. Number of sons of Mr. Jagdish is six times the number of his daughter (s).

A If the data in both statement I and II together are needed to answer the question. Correct Answer Incorrect Answer
B If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question. Correct Answer Incorrect Answer
C If the data either in statement I alone or in statement II alone is sufficient to answer the question Correct Answer Incorrect Answer
D If the data even in both the statement I and II together are not sufficient to answer the question Correct Answer Incorrect Answer
E If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question. Correct Answer Incorrect Answer

Solution

From I: Number of sons = 6, Number of daughters = 1. Hence, total children  = 7. From II: Suppose number of daughters = x; So, the number of sons = 6x, We have 2 possibilities for daughters 1 or 6. So, if number of daughter = 1, and number of sons is 6. Which is 6 times and if number of daughter = 6, and number of sons is 6. Which is not 6 times. So statement I is required.
