D. can't be determined

Answer

To find the average number of paise per person, we will first calculate the total amount of paise each person has and then find the average.

### Step 1: Calculate the total paise for each person

1. **Person A:**
- Number of coins = 50
- Denomination = 10 paise
- Total paise = Number of coins × Denomination = 50 × 10 = 500 paise

2. **Person B:**
- Number of coins = 10
- Denomination = 50 paise
- Total paise = Number of coins × Denomination = 10 × 50 = 500 paise

3. **Person C:**
- Number of coins = 20
- Denomination = 25 paise
- Total paise = Number of coins × Denomination = 20 × 25 = 500 paise

4. **Person D:**
- Number of coins = 25
- Denomination = 20 paise
- Total paise = Number of coins × Denomination = 25 × 20 = 500 paise

### Step 2: Calculate the total paise for all persons

Total paise = Total paise of A + Total paise of B + Total paise of C + Total paise of D
Total paise = 500 + 500 + 500 + 500 = 2000 paise

### Step 3: Calculate the total number of persons

Total number of persons = 4 (A, B, C, D)

### Step 4: Calculate the average number of paise per person

Average paise per person = Total paise / Total number of persons
Average paise per person = 2000 paise / 4 = 500 paise

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