If the hours rained in Tuesday = a
Then, the number of hours it rained on Monday = 2a
Number of hours of rain on Wednesday = 4*2a = 8a
Hence, the ratio of Monday : Tuesday : Wednesday = 2a : a : 8a
we need to find: 11a ?
Statement 1:
It rained for 30 minutes more on Monday than on Tuesday.
2a - a = 30 minutes.
a = 30 minutes.
we can find 11a.
Hence, Sufficient.
Statement 2:
It rained for 3.5 hours longer on Wednesday than on Tuesday.
8a - a = 7a = 3.5 hours.
a = 30 minutes.
we can find 11a.
Hence, Sufficient.

Explanation:
Let the duration of rain on Tuesday be T minutes.
The duration of rain on Monday = 2T minutes.
The duration of rain on Wednesday = 4 x 2T = 8T minutes.
The total duration of rain = T + 2T + 8T = 11T minutes.
We need to find whether the value of 11T can be determined.
Statement (1)
2T = 30 + T
Since it is possible to determine the exact value of T, it is also possible to determine the exact duration of rain over the three days. Hence, Statement (1) is sufficient.
Statement (2)
8T = (3.5 x 60) + T
Since it is possible to determine the exact value of T, it is also possible to determine the exact duration of rain over the three days. Hence, Statement (2) is sufficient.
D is the correct answer choice.
