The average income of Arun, Bala and Chitra is Rs. 12,000 per month an...
Given:
- Average income of Arun, Bala and Chitra = Rs. 12,000 per month
- Average income of Bala, Chitra and David = Rs. 15,000 per month
- Average salary of David = 2 * Average salary of Arun

To find:
- Average salary of Bala and Chitra

Solution:
Let's assume the salary of Arun, Bala, and Chitra as A, B, and C respectively.
Based on the given information, we can set up the following equations:

A + B + C = 36,000 ...(1) [Since the average income of Arun, Bala and Chitra is Rs. 12,000 per month]
B + C + 2A = 45,000 ...(2) [Since the average income of Bala, Chitra and David is Rs. 15,000 per month and the average salary of David is twice that of Arun]

Subtracting equation (1) from equation (2), we get:

A = 9,000

Substituting the value of A in equation (1), we get:

B + C = 27,000

Therefore, the average salary of Bala and Chitra = (B + C)/2 = 27,000/2 = Rs. 13,500

Hence, the correct answer is option (d) 13,500.
