C) $1,000 at 2%; $1,800 at 4%
Answer by palanisamy(496)   (Show Source):
You can put this solution on YOUR website! Let the man invest an amount x at 2% interest.
Then, he invests an amount (x+800) at 4% interest.
Total simple interest for one year is
x*2/100 + (x+800)*4/100 = 92
2x+4x+3200 = 9200
6x = 9200-3200
6x = 6000
x = 1000
So the man invested $ 1000 at 2% interest and $ 1800 at 4% interest.
