Answer

To solve the equation \( 60\% \text{ of } 250 - ? = 75 \), we will follow these steps:

### Step 1: Calculate 60% of 250
To find 60% of 250, we can convert the percentage into a fraction:
\[ 60\% = \frac{60}{100} = 0.6 \]
Now, multiply this fraction by 250:
\[ 0.6 \times 250 = 150 \]

### Step 2: Substitute the value back into the equation
Now, we substitute the value we found back into the equation:
\[ 150 - ? = 75 \]

### Step 3: Isolate the question mark
To isolate the question mark, we can rearrange the equation. First, add \( ? \) to both sides:
\[ 150 = 75 + ? \]
Next, subtract 75 from both sides:
\[ 150 - 75 = ? \]
\[ ? = 75 \]

### Conclusion
Thus, the value of the question mark is:
\[ ? = 75 \]
