An investor invested some money in 2 separate schemes: A and B. Scheme A will yield 30% of the capital within a year, and scheme B will yield 50% of the capital within a year. If he invested $300 in scheme A and $200 in B, how much more money will he have in scheme A than in B after a year, provided he does not withdraw anything? Let's answer step by step:

After a year, scheme A will yield 30% of his capital which is (30 / 100) * $300 = $90. In addition to his capital, he will have $90 + $300 = $390 in scheme A. After a year, scheme B will yield 50% of his capital which is (50 / 100) * $200 = $100. In addition to his capital, he will have $100 + $200 = $300 in scheme B. After a year, he will have $390 - $300 = $90 in scheme A more than in scheme B. The answer: 90.
