Answer:
The answer is 20 hours to complete the project.
Explanation:
Project evaluation and review technique is used to estimate the time it takes to execute a project. It makes use of 3 data points (worst estimate, most likely estimate, and best estimate) to make a final estimate.
Using the formula for project estimation below
P Estimate= {(Best estimate)+4(Most likely est)+(Worst estimate)}/6
P Estimate= to{(15+(4*20)+25)}/6
= (120)/6
= 20 hours
