You are given a question and two statements. Identify which of the statements is/are sufficient to answer the question.
Question: Meenu has 5 boards of 3 different shapes - square, rectangular and circular. How many circular boards does she have?
Statements:
1. There are 3 square boards.
2. The number of rectangular boards is one-third of the number of square boards.

Options

A. A. Statements 1 and 2 together are sufficient.
B. B. Statement 1 alone is sufficient.
C. C. Statement 2 alone is sufficient.
D. D. Statements 1 and 2 together are not sufficient.

Answer

To determine how many circular boards Meenu has, we will analyze the given statements step by step.

### Step-by-Step Solution:

1. **Understand the total number of boards**:
- Meenu has a total of 5 boards. These boards can be of three different shapes: square, rectangular, and circular.

2. **Analyze Statement 1**:
- Statement 1 states that there are 3 square boards.
- If there are 3 square boards, we can denote the number of square boards as \( S = 3 \).

3. **Analyze Statement 2**:
- Statement 2 states that the number of rectangular boards is one-third of the number of square boards.
- Since we have already established that \( S = 3 \), we can calculate the number of rectangular boards \( R \) as follows:
\[ R = \frac{1}{3} \times S = \frac{1}{3} \times 3 = 1 \]

4. **Calculate the number of circular boards**:
- We know the total number of boards is 5. Therefore, we can express the number of circular boards \( C \) as:
\[ C = \text{Total boards} - (S + R) = 5 - (3 + 1) = 5 - 4 = 1 \]

5. **Conclusion**:
- From the calculations, we find that Meenu has 1 circular board.

### Summary:
- The number of circular boards Meenu has is **1**.
