D. can't be determined

Answer

To find the average number of paise per person, we will follow these steps:

### Step 1: Calculate the total amount of paise for each person.
- **A** has 50 coins of 10 paise:
\[ \text{Total paise for A} = 50 \times 10 = 500 \text{ paise} \]

- **B** has 10 coins of 50 paise:
\[ \text{Total paise for B} = 10 \times 50 = 500 \text{ paise} \]

- **C** has 20 coins of 25 paise:
\[ \text{Total paise for C} = 20 \times 25 = 500 \text{ paise} \]

- **D** has 25 coins of 20 paise:
\[ \text{Total paise for D} = 25 \times 20 = 500 \text{ paise} \]

### Step 2: Calculate the total amount of paise for all persons.
Now, we add the total paise of all four persons:
\[ \text{Total paise} = 500 + 500 + 500 + 500 = 2000 \text{ paise} \]

### Step 3: Count the number of persons.
The number of persons is 4 (A, B, C, and D).

### Step 4: Calculate the average number of paise per person.
To find the average, we divide the total paise by the number of persons:
\[ \text{Average} = \frac{\text{Total paise}}{\text{Number of persons}} = \frac{2000}{4} = 500 \text{ paise} \]

### Final Answer:
The average number of paise per person is **500 paise**.
