Consider the following work sampling data: Working time = 60%, average rating = 90%, relaxation allowance = 12.5% actual output during the study = 1000 units and study duration = 480 minutes. The standard time per unit (in minutes) will be
  • a)
    0.2592
  • b)
    0.2916
  • c)
    0.3240
  • d)
    0.4860
Correct answer is option 'B'. Can you explain this answer?

Consider the following work sampling data: Working time = 60%, average...
Observed time = 480 x 0.6 
= 288 mins.
Normal time = Observed time x rating  factor
= 288 x 0.9
= 259.2 mins.
Standard time = Normal time x allowances 
= 259.2 x 1.125 
= 291.6 minutes 
∴ The standard time per unit

Consider the following work sampling data: Working time = 60%, average...
Calculation of Standard Time per Unit
1. Working time: Working time = 60%
2. Rating factor: Average rating = 90%
3. Relaxation allowance: Relaxation allowance = 12.5%
4. Actual output: Actual output during the study = 1000 units
5. Study duration: Study duration = 480 minutes

Calculating the Standard Time per Unit:
- Standard time per unit = (Study duration * Working time * Rating factor) / (Actual output * (1 - Relaxation allowance))
- Standard time per unit = (480 * 0.60 * 0.90) / (1000 * (1 - 0.125))
- Standard time per unit = (259.2) / (1000 * 0.875)
- Standard time per unit = 259.2 / 875
- Standard time per unit = 0.2916 minutes
Therefore, the standard time per unit is 0.2916 minutes. Hence, option b) 0.2916 is the correct answer.
