A man invests some money partly in 9% stock at 96 and partly in 12% stock at 120. To obtain equal dividends from both, he must invest the money in the ratio: Answer: 16 : 15

For an income of Re.. 1 in 9% stock at 96, investment = Rs. [96/9] = Rs. 32/3. For an income Re. 1 in 12% stock at 120, investment = Rs. [120/12] = Rs. 10. ∴ Ratio of investments = 32/3 : 10 = 32 : 30 = 16 : 15.
