3. The sum of the accumulated value of 1 at the end of three years at a certain effective rate of interest i, and the present value of 1 to be paid at the end of three years at an effective rate of discount numerically equal to i is 2.0096. Find the rate i. 4. Fund Faccumulates at a rate of 8(t) = 1/(1+t). Fund G accumulates at a tare of 8(t) = 4t/(1+t2). Both funds have the same amount at t = 0. At what time will the difference between the amounts of the two funds be a maximum? 3.
