Direction (1-3): Each of these questions is followed by two statements, labelled I and II, in which certain data are given. In these questions you do not actually have to compute an answer, but rather you have to decide whether the data given in the statements are sufficient for answering the given questions. Using the data given in the statements plus your knowledge of Mathematics and everyday facts (such as the number of days in a month) you are to choose your answer as:


(1) if the statement I alone is sufficient but statement II alone is not sufficient to answer the question ;
(2) if the statement II alone is sufficient but statement I alone is not sufficient to answer the question ;
(3) if both the statements I and II together are sufficient to answer the question asked but neither of the statements alone is sufficient.
(4) if the statements I and 11 together are not sufficient to answer the question asked and additional data specific to the problem are needed.
