weight =mg
g is gravitational acceleration which is 9.8 but opposite acceleration is also takking place so take g=9.8-2 which is 7.8 so weight will be mass×g ok them simply compare the percentage of the first time with lift at rest and then lift with accelration

Increse 40%
decrease 40%
decrease 40%
ok then compare the weight of lift with accelration to with lift at rest
ok thk u
ok i wish it help you

The lift is moving up that is why the weight will be equal to W=m(g+a). So the apparent weight will be increased .
