I see the problem in the image. Let me break it down and solve it step by step:

### Problem:
A vendor sold 20% of his total pommeracs on Friday at the market. On Saturday, he sold 50% of the remainder. He was left with 120 pommeracs unsold.

#### Questions:
1. **(a)** What percentage of the remainder did he sell on Saturday?
2. **(b)** What percentage of his pommeracs remained after both Friday and Saturday sales?
3. **(c)** How many pommeracs did he have before he started his sales at the market?

---

### Solving step by step:

Let the total number of pommeracs the vendor started with be \( x \).

1. **Friday Sales**:
   - The vendor sold 20% of his total stock on Friday.
   - This means he sold \( 0.2x \) on Friday.
   - The remaining stock after Friday = \( x - 0.2x = 0.8x \).

2. **Saturday Sales**:
   - On Saturday, he sold 50% of what remained from Friday.
   - This means he sold \( 0.5 \times 0.8x = 0.4x \) on Saturday.
   - After Saturday, he was left with \( 0.8x - 0.4x = 0.4x \).

3. **Final Information**:
   - We know that after both sales, he had 120 pommeracs left.
   - Therefore, \( 0.4x = 120 \).

### Solving for \( x \):

\[
0.4x = 120
\]

\[
x = \frac{120}{0.4} = 300
\]

The vendor originally had **300 pommeracs** before he started selling.

### Answering the Questions:

1. **(a)** What percentage of the remainder did he sell on Saturday?
   - The remainder after Friday was \( 0.8x \) and he sold \( 0.4x \) on Saturday.
   - The percentage sold on Saturday = \( \frac{0.4x}{0.8x} \times 100 = 50\% \).

2. **(b)** What percentage of his pommeracs remained after both Friday and Saturday sales?
   - After both days, the vendor was left with \( 0.4x = 120 \).
   - The percentage remaining = \( \frac{120}{300} \times 100 = 40\% \).

3. **(c)** How many pommeracs did he have before he started?
   - The vendor originally had **300 pommeracs**.

---

### Final Answers:
- **(a)** 50%
- **(b)** 40%
- **(c)** 300 pommeracs

Here are 5 related questions for practice:
1. If the vendor had sold 25% on Friday instead of 20%, how many would remain after Saturday?
2. How many pommeracs did he sell in total across both days?
3. What fraction of the original stock was left after Friday's sales?
4. If the vendor sold 30% of his total on Friday and 50% of the remainder on Saturday, how many would remain?
5. How much more would the vendor have if he sold only 10% on Friday?

**Tip:** When calculating percentages, always ensure to convert the percentage into its decimal form before applying it to any given quantity.
