    Step-by-step explanation:

    Mass of the man  m=40kg

    Acceleration of lift in upward direction a=2m/s2

    Let the weight shown by machine be N.

    Equation of motion for the body :   ma=N−mg

    We get  N=m(a+g)    

    ∴  N=(40)(2+10)=480  N

    Thus weight of the man recorded by machine W′=gN

    ∴  W′=10480=48 kg
