Options

A. 12
B. 24
C. 36
D. 48

Explanation

To solve the problem of how many numbers greater than 40,000 can be formed from the digits 2, 4, 5, 5, and 7, we will follow these steps:

### Step 1: Calculate the total arrangements of the digits
We have the digits 2, 4, 5, 5, and 7. The total number of arrangements of these digits can be calculated using the formula for permutations of multiset:

\[ \text{Total arrangements} = \frac{n!}{p_1! \cdot p_2! \cdots p_k!} \]
