Multiple choice

A welding operation is time-studied during which a operator was pace-rated as 120%. The operator took, on an average, 8 minutes for producing the weld-joint. If a total of 10% allowances are allowed for this operation, the expected standard production rate of the weld-joint (in units per 8 hour day) is

  1. 45

  2. 50

  3. 55

  4. 60
