Each Of the questions below consists of question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and—
Give answer a: if the data in statement I alone are sufficient to answer the
question, while the data in statement 11 alone are not sufficient to answer the question.
Give answer b: if the data in statement II alone are sufficient to answer the
question, while the data in statement I alone are not sullicient to answer the question.
Give answer c: if the data either in statement I alone or in statement II alone are sufficient to answer the question.
Give answer d: if the data given in both the statements I & II together are not sufficient to answer the question. and
Give answer e: if the data in both the statements I & II together are necessary to answer the question
How many sisters does D have?
I. D’s mother has four children.
II. K and T are brothers of E.
I : D's mother has 4 children, which means that D has 3 siblings, of whom we do not know the gender of.
Thus, I alone is not sufficient.
II : There is no data related to D.
Thus, II alone is not sufficient.
I & II : Even after combining the two statements, we just know that D has 3 siblings, and we can't determine the relation between 'K,T,E' and 'D'.
Thus, I & II together are not sufficient.
