Did anybody besides me have trouble getting the correct IRR on a question that had cash flows of t=0 -100, t=1 30, t=2 40, t=3 40, t=4 30 with a required rate of return of 13%? The only answer options are 19.25% and 14.25% and I keep getting 14.9%. Am I going crazy here or what?

Based upon the information youâ€™ve providedâ€¦ CF0 = -100 CF1 = 30 CF2 = 40 CF3 = 40 CF4 = 30 n = 4 i = 13 Calculated NPV = 3.996 Calculated IRR = 14.895
