Using Taylor’s differential piece rate system, find the earnings of a worker, W form the following data:

Standard time per unit                                                                                12 minutes

Normal rate per hour (in a 8 hours day)                                                 Rs 20

W produced                                                                                                  37 units

Differential to be applied: 83% of piece rate below standard and 120% above standard.
