Explanation

Total amount = Rs. 20,000. First loan = Rs. 12,000 at 8% p.a. Interest from first loan = 12000 × 0.08 = Rs. 960. Desired profit on whole = 10% of 20000 = Rs. 2000. So second loan interest needed = 2000 - 960 = Rs. 1040. Second loan amount = 20000 - 12000 = Rs. 8000. Rate = 1040/8000 = 0.13 = 13%.
