Given:
- A invested Rs 20,000
- B joined after 4 months with some capital
- Profit is divided in the ratio 5:3 after a year

To find:
- How much did B invest?

Approach:
- Calculate the profit made by the business in a year
- Divide the profit in the ratio of 5:3 to find the share of A and B
- Use the share ratio to find the total investment made by both A and B
- Subtract A's investment to find B's investment

Solution:
Let's assume that B invested Rs x when he joined the business after 4 months.

We know that profit is divided in the ratio of 5:3. Therefore, let's assume that the total profit made by the business in a year is Rs y.

Profit share of A = (5/8) * y
Profit share of B = (3/8) * y

We also know that A invested Rs 20,000 for the entire year. Therefore, the total investment made by both A and B is:
- For A: Rs 20,000 * 12 months = Rs 2,40,000
- For B: Rs x * 8 months (since B joined after 4 months) = Rs 8x

Now, we can use the share ratio to find the total profit made by the business:
- (5/8) * y = Rs 2,40,000
- y = (8/5) * Rs 2,40,000
- y = Rs 3,84,000

Substituting the value of y, we can find the profit share of A and B:
- Profit share of A = (5/8) * Rs 3,84,000 = Rs 2,40,000
- Profit share of B = (3/8) * Rs 3,84,000 = Rs 1,44,000

Finally, we can use the profit share to find the total investment made by both A and B:
- For A: Rs 2,40,000 / (12 months * 1,000) = Rs 20
- For B: Rs 1,44,000 / (8 months * 1,000) = Rs 18

Therefore, B invested Rs 18,000 when he joined the business after 4 months.

Answer: Option B. Rs 18,000
