A company’s sales figures have changed over the past two months. In the first month, the company sold 200 units of a product. In the following month, sales increased to 250 units. However, in the next month, the sales decreased to 200 units again due to various factors.

What is the percent decrease in sales from the second month to the third month?
A.15%
B.20%
C.25%
D.30%

Let's calculate both the percent increase and the percent decrease using the given information.

### 1. Percent increase from the first month to the second month:

To calculate the percent increase, we use the formula:

\[
\text{Percent Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100
\]

- **Old Value** = 200 units (first month)
- **New Value** = 250 units (second month)

\[
\text{Percent Increase} = \frac{250 - 200}{200} \times 100 = \frac{50}{200} \times 100 = 25\%
\]

So, the percent increase from the first month to the second month is **25%**.

### 2. Percent decrease from the second month to the third month:

For percent decrease, the formula is the same as for percent increase, but it reflects a reduction:

\[
\text{Percent Decrease} = \frac{\text{Old Value} - \text{New Value}}{\text{Old Value}} \times 100
\]

- **Old Value** = 250 units (second month)
- **New Value** = 200 units (third month)

\[
\text{Percent Decrease} = \frac{250 - 200}{250} \times 100 = \frac{50}{250} \times 100 = 20\%
\]

So, the percent decrease from the second month to the third month is **20%**.

### Final Answers:
1. Percent increase from first to second month: **B. 25%**
2. Percent decrease from second to third month: **B. 20%**
