II. Select which of the statement(s) is/are sufficient to answer the question. Question: How many captains are there between Winnie and Dyson in a row of captains, all facing north? Statements: I. Winnie is 15th from the extreme left end of the row. II. Dyson is exactly in the middle of the row and there are ten captains to his right.Solution
Statement-I: Winnie is 15th from the extreme left end of the row.  Statement-II: Dyson is exactly in the middle of the row and there are ten captains to his right.  So, Dyson ranks 11th from the left.  When combining Statement I and II:  Total captains between Winnie and Dyson = Winnie’s rank from left – Dyson’s rank from left – 1 Total captains between Winnie and Dyson = 15 – 11 – 1 = 15 – 12 = 3  So, there are 3 captains between Winnie and Dyson. Thus, both I and II together are sufficient. Hence, the correct answer is (D).
