The number of visits that a junior sales representative makes in a 2-year period is approximately what percent greater than the number of visits that a senior representative makes in the same period?

Option A:

10%

Option B:

25%

Option C:

33%

Option D:

50%

Option E:

67%

### 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%
