10%

Option B:

25%

Option C:

Option D:

50%

Option E:

### Difficulty Level

Medium### Solution

Option D is the correct answer.

### Option Analysis

For seniors, the time of visit is 30 days. The rate is 1/30. Similarly, the rate of visit for junior is 1/20.

The 2 yrs has no significance in this case. The rate stays the same for every time interval.

(({1/20} – {1/30})/ {1/30}) * 100 = 50%
