Question: Is Sunday ≥ 100?
Given: If Tuesday = x, then Monday = 2x
Statement 1: None of the weekdays was chosen by more than 150 visitors.
i.e. Sunday visitors will be least when total visitors on other days are maximum i.e. 150
i.e. Maximum Visitors on 6 days from Monday to Saturday = 150*6 = 900
i.e. Minimum Visitors on Sunday = 1000 - 900 = 100
SUFFICIENT
Statement 2: None of the weekdays was chosen by fewer than 75 visitors
NOT SUFFICIENT

I think there is a flaw in the question.
From the question:
Total visitors = 1000
Monday Visitors = 2 * Tuesday Visitors
(1) number of Daily visitors < 150, If all days have the maximum number of visitors of 150 and to respect the relation between the number of visitors on Monday and Tuesday, we would have:
Sun, Mon, Wed, Thu, Fri e Sat = 150 (6 * 150 = 900 visitors)
Tuesday = 75 visitors
Total = 975 visitors (and NOT 1000 visitors!)
It does not respect the total number of visitors
(2) number of Daily visitors > 75, If all days have the minimum number of visitors of 75 and to respect the relation between the number of visitors in Monday and Tuesdays, we would have:
Sun, Tue, Wed, Thu, Fri e Sat = 75 (6 * 75 = 450 visitors)
Monday = 150 visitors
Total = 600 visitors : 400 visitors left to distribute on the others days, but we don't have any more information to distribute these visitors.
NOT SUFFICIENT
Both together we have the same problem from (1): It does not respect the total number of visitors
