D. 11

Answer

To solve the problem, we need to calculate the total cost of the cards Raman bought and then determine how many Rs. 10 notes he used for payment.

### Step-by-Step Solution:

1. **Identify the Prices of the Cards:**
- Type 1: Rs. 2.00
- Type 2: Rs. 3.50
- Type 3: Rs. 4.50
- Type 4: Rs. 5.00

2. **Determine the Quantity of Each Type of Card:**
- Raman bought 5 cards of two types and 10 cards of the other two types.
- Let's assume he bought:
- 5 cards of Type 2 (Rs. 3.50)
- 5 cards of Type 3 (Rs. 4.50)
- 10 cards of Type 1 (Rs. 2.00)
- 10 cards of Type 4 (Rs. 5.00)

3. **Calculate the Total Cost:**
- Cost of 10 cards of Type 1 (Rs. 2.00):
\[ 10 \times 2 = 20 \text{ Rs.} \]
- Cost of 5 cards of Type 2 (Rs. 3.50):
\[ 5 \times 3.5 = 17.5 \text{ Rs.} \]
- Cost of 5 cards of Type 3 (Rs. 4.50):
\[ 5 \times 4.5 = 22.5 \text{ Rs.} \]
- Cost of 10 cards of Type 4 (Rs. 5.00):
\[ 10 \times 5 = 50 \text{ Rs.} \]

4. **Sum Up All the Costs:**
\[ \text{Total Cost} = 20 + 17.5 + 22.5 + 50 = 110 \text{ Rs.} \]

5. **Calculate the Number of Rs. 10 Notes:**
- To find out how many Rs. 10 notes are needed to pay Rs. 110:
\[ \text{Number of notes} = \frac{110}{10} = 11 \text{ notes.} \]

### Final Answer:
Raman paid **11 Rs. 10 notes**.
