**Reiny**, Thursday, October 21, 2010 at 8:50amSince the total profit was 620 which included the loss of 55, there must have been a profit of 675 from the first investment.

Assuming we are looking only at the one year, the question now becomes a simple interest problem where

P ?

I = 675

R = .12

T = 1

P = I/(RT)

= 675/.12 = 5625

so he invested $5625 at 12% ( the winner) and

$2375 in the losing investment.
