CF 0 = CF1 / 1+r + CF2 / (1+r)^2 + CF3 / (1+r)^3CF 0 = -100 + 1.8 = -98.20CF 1 = 7.5CF 2 = 7.5CF 3 = 107.5solve for r = 8.20% (almost 8.19% )

If you don't want to use a solver for the equation (especially in more complicated cases), you can just write in Excel:-98.207.57.5107.5in A1:A4 and find the effective return with =IRR(A1:A4)HTHJungix
