Explanation

Total investment = Rs. 40,000. First loan = Rs. 24,000 at 8% p.a. Second loan = Rs. 16,000. Total desired profit = 10% of Rs. 40,000 = Rs. 4,000. Profit from first loan = 8% of Rs. 24,000 = Rs. 1,920. Required profit from second loan = Rs. 4,000 - Rs. 1,920 = Rs. 2,080. Rate for second loan = (2080/16000) × 100 = 13% p.a.
