Ankit’s position from the right end? I. Akash is fourth to the right of Ankit and 24th from the left end of the row. II . Moni is third to the left of Ankit and 15th from the right end of the row. Directions (33-37): Each of the questions below consists of a 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 the question and both the statements and give answer 1) 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. 2) 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. 3) If the data either in statement I alone or in statement II alone are sufficient to answer the question. 4) If the data in both statement I and II together are not sufficient to answer the question. 5) If the data in both statement I and II together are necessary to answer the question.Solution
