Explanation:

The Boy gains Gravitational Potential Energy (GPE). Whether he walks upto the 4th floor or uses a lift to take him to the 4th floor, he will gain the same amount of GPE because

GPE = m x g x h

m: Mass of the Person

g : Acceleration due to gravity

h : Perpendicular distance of person from Ground

SInce h will be same in both the cases GPE will be same...
