The problem asks for the difference in income and expenditure of Foreign Banks in 2022-2023, given that their income and expenditure in 2020-2021 were equal and amounted to ₹60,000 crore.

### Step-by-step solution:

1. **Income Calculation:**
   - The income of Foreign Banks in 2020-2021 was ₹60,000 crore.
   - The income increased by **9%** in 2021-2022 and by **12%** in 2022-2023.
   
   So, we calculate the income in 2022-2023:

   \[
   \text{Income in 2021-2022} = 60,000 \times \left(1 + \frac{9}{100}\right) = 60,000 \times 1.09 = 65,400 \, \text{crore}
   \]
   
   \[
   \text{Income in 2022-2023} = 65,400 \times \left(1 + \frac{12}{100}\right) = 65,400 \times 1.12 = 73,248 \, \text{crore}
   \]

2. **Expenditure Calculation:**
   - The expenditure of Foreign Banks in 2020-2021 was also ₹60,000 crore.
   - The expenditure increased by **4%** in 2021-2022 and by **11%** in 2022-2023.
   
   So, we calculate the expenditure in 2022-2023:

   \[
   \text{Expenditure in 2021-2022} = 60,000 \times \left(1 + \frac{4}{100}\right) = 60,000 \times 1.04 = 62,400 \, \text{crore}
   \]
   
   \[
   \text{Expenditure in 2022-2023} = 62,400 \times \left(1 + \frac{11}{100}\right) = 62,400 \times 1.11 = 69,264 \, \text{crore}
   \]

3. **Difference between Income and Expenditure in 2022-2023:**

   \[
   \text{Difference} = 73,248 - 69,264 = 3,984 \, \text{crore}
   \]

Thus, the difference between income and expenditure of Foreign Banks in 2022-2023 is **₹3,984 crore**.

### The correct answer is option (1): ₹3,984 crore.

Do you need further clarification or additional details?

Here are 5 related questions to deepen your understanding:
1. How would the result change if the expenditure increase percentage were 5% instead of 4% in 2021-2022?
2. How can we generalize the approach to calculate differences for any other type of bank listed?
3. What would be the total income of Foreign Banks from 2020 to 2023?
4. How would the difference between income and expenditure change if the income percentage increase was lower than the expenditure percentage increase?
5. Can you derive a formula to quickly compute percentage increases over multiple years?

**Tip:** When dealing with compound percentage increases over multiple years, always calculate each year's result incrementally by applying the percentage to the previous year's value.

If the expenditure of foreign Banks in 2020-2021 is equal to their income in that year and is equal to ₹60,000 crore, then in 2022-2023, what is the difference in income and expenditure of Foreign Banks?

Calculate the difference between the income and expenditure of Foreign Banks in 2022-2023, given that their income and expenditure in 2020-2021 was ₹60,000 crore. The solution involves percentage growth calculations for both income and expenditure.
