Question: Day Trader wants to invest a sum of money that would generate an annual yield of at least $10,000.
Two stock groups are available: blue chips and high tech, with average annual yields of 10% and 25%, respectively. Though high-tech stocks provide higher yield, they are more risky, and Trader wants to limit the amount invested in these stocks to no more than 60% of the total investment.
What is the minimum amount Trader should invest in each stock group to accomplish the investment goal?
Please show me all the working and give the answer of the given problem.
