Let's solve each part of the problem step by step:

### Given Data:
- Marked price of the washing machine = Rs. 40,000
- Discount percentage = 10%
- Purchase price for the shopkeeper = Rs. 32,000

---

### a. **Find the discount given to Ridhi on the purchase of the washing machine:**

The discount is calculated as:

\[
\text{Discount} = \left( \frac{\text{Discount \%}}{100} \right) \times \text{Marked Price}
\]

Substituting the values:

\[
\text{Discount} = \left( \frac{10}{100} \right) \times 40,000 = 4,000
\]

So, the discount given to Ridhi is **Rs. 4,000**.

---

### b. **Find the price she paid for the washing machine:**

The price paid by Ridhi is the marked price minus the discount:

\[
\text{Price Paid} = \text{Marked Price} - \text{Discount}
\]

Substituting the values:

\[
\text{Price Paid} = 40,000 - 4,000 = 36,000
\]

So, the price Ridhi paid for the washing machine is **Rs. 36,000**.

---

### c. **If the purchase price for the shopkeeper is Rs. 32,000, find the amount gained or lost by the shopkeeper:**

The shopkeeper's gain or loss is calculated as:

\[
\text{Gain/Loss} = \text{Selling Price} - \text{Cost Price}
\]

Where:
- Selling Price (Price Paid by Ridhi) = Rs. 36,000
- Cost Price (Purchase Price for the shopkeeper) = Rs. 32,000

Substituting the values:

\[
\text{Gain/Loss} = 36,000 - 32,000 = 4,000
\]

Since the result is positive, the shopkeeper gained **Rs. 4,000**.

---

### Final Answers:
- a) **Discount** = Rs. 4,000
- b) **Price Paid by Ridhi** = Rs. 36,000
- c) **Shopkeeper's Gain** = Rs. 4,000
