Let A = { b,d,e,f }, B = { c,d,g,h} and C = {e,f,g,h} .Find :
C -A

Answer

To find \( C - A \), we need to identify the elements that are in set \( C \) but not in set \( A \).

### Step-by-Step Solution:

1. **Identify the sets**:
- Set \( A = \{ b, d, e, f \} \)
- Set \( C = \{ e, f, g, h \} \)

2. **List the elements of set \( C \)**:
- The elements of set \( C \) are \( e, f, g, h \).

3. **Identify the elements of set \( A \)**:
- The elements of set \( A \) are \( b, d, e, f \).

4. **Determine which elements of \( C \) are not in \( A \)**:
- Compare the elements of \( C \) with those in \( A \):
- \( e \) is in \( A \)
- \( f \) is in \( A \)
- \( g \) is not in \( A \)
- \( h \) is not in \( A \)

5. **List the elements that are in \( C \) but not in \( A \)**:
- The elements \( g \) and \( h \) are in \( C \) but not in \( A \).

6. **Write the result**:
- Therefore, \( C - A = \{ g, h \} \).

### Final Answer:
\[ C - A = \{ g, h \} \]
