Explanation : Compute the NPV of both the projects at 10% discount rate. Using the
financial calculator,
enter CF for Years 0 – 4.
Project X: CF0 = -2340, CF1 = 240, CF2 = 729, CF3 = 505, CF4 = 3680,
I = 10, CPT NPV. NPV = $1,373.56.
Project Y: CF0 = -2340, CF1 = 240, CF2 = 729, CF3 = 990, CF4 =
3115, I = 10, CPT NPV. NPV = $1,352.05.
B is correct because Project X has a higher NPV and the projects are mutually
exclusive, only Project X should be accepted.
