Detailed 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).
