Hi,

I just tried doing D10Q4. But the suggested ans seems to be wrong in part (a).

While calculating the OAR, they have only considered the direct labour hrs p.u and ignored the machine hrs p.u. Can’t it be argued that labour is required to run the machines and therefore while calculating the OAR the machine hrs p.u should be added to the labour hrs p.u to get the annual labour hrs p.u?
