A soldering operation was work sampled over two days (16 hours) during which an employee soldered 108 joints, actual working time was 90% of total time and the performance rating was estimated to be 120 percent. If the contract provides allowance of 20 percent of the total time available, the standard time for the operation would be
  • a)
    5 minutes
  • b)
    12 minutes
  • c)
    20 minutes
  • d)
    22 minutes
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A soldering operation was work sampled over two days (16 hours) during...
Total time = 16 × 60 minutes
Actual time = 
Normal Time = 864 × 1.2 = 1036.8 minutes
Standard time = Normal time + Allowance
Standard time
= = 1296 minute

A soldering operation was work sampled over two days (16 hours) during...
Standard time is the time required to complete a task under normal conditions, taking into account factors such as efficiency, performance, and allowances. In this case, we need to determine the standard time for a soldering operation based on the given information.

1. Given data:
- Total time available: 16 hours (2 days)
- Joints soldered: 108
- Actual working time: 90% of total time
- Performance rating: 120%
- Allowance: 20% of total time

2. Calculating the actual working time:
The actual working time is given as 90% of the total time available. Therefore,
Actual working time = 0.9 * 16 hours = 14.4 hours

3. Calculating the effective working time:
The performance rating is given as 120%, which means the employee is working 20% more efficiently than the standard. Therefore,
Effective working time = Actual working time * (Performance rating / 100)
Effective working time = 14.4 hours * (120 / 100) = 17.28 hours

4. Calculating the standard time:
The standard time is the sum of the effective working time and the allowance. Therefore,
Standard time = Effective working time + Allowance
Standard time = 17.28 hours + (20% of 16 hours)
Standard time = 17.28 hours + (0.2 * 16 hours)
Standard time = 17.28 hours + 3.2 hours
Standard time = 20.48 hours

5. Converting standard time to minutes:
We need to convert the standard time from hours to minutes.
Standard time = 20.48 hours * 60 minutes/hour
Standard time = 1228.8 minutes

6. Rounding off the standard time:
Since the options provided are in minutes, we need to round off the standard time to the nearest minute.
Standard time = 1230 minutes

7. Identifying the correct option:
The correct option is 12 minutes (option B), as it is the closest to the rounded-off standard time of 1230 minutes.

Therefore, the standard time for the soldering operation is approximately 12 minutes.
