A man invested a total of Rs 10000 in two schemes. Scheme A gives 8% and scheme B gives 10% simple interest per year. After one year he earned Rs 920 as interest. How much (in Rs) did he invest in scheme A?

Question

Accepted Answer

Rs 4000. a + b = 10000, 0.08a + 0.10b = 920. Multiply: 8a + 10b = 92000; and 8a + 8b = 80000. Subtract: 2b = 12000, b = 6000, a = 4000.
