Answer:
since you are in a non inertial frame. an additional force (pseudo force ) will be applied opposite to direction of acceleration . so if you are going down the upward pseudo force will reduce your weight. and while going upward your weight will increase

Explanation:
When the lift accelerates upward, a pseudo force will act on the body in the downward direction in addition to the weight. So the apparent weight will increase.
If lift is going with uniform speed, the force acting on the body will be weight of the person. So the apparent weight will be same as the real weight.
