Question

 An industry produces 300 spark plugs in one shift of 8 hours. If the standard time per piece is 1.5 minute, the productivity would be
1. 3/4
2. 5/8
3. 7/16
4. 15/16

Answer 1

Correct Answer - Option 4 : 15/16

Concept:

\(Productivity=\frac{Net\;Production\;Obtained}{Standard\;Production\;Possible}\)

Calculation:

Given:

Time of one shift = 8 hours = (8 x 60) min = 480 min.

Standard time per piece = 1.5 min

Spark plugs produced in one shift (8 hours) = 300 pieces

Total spark plug that can be made in 480 min i.e.

Standard Production Possible = \(\frac{Total\;Time\;Available}{Time\;required\;per\;pieces}=\frac{480}{1.5}=320\) pieces

Net production obtained by industry in 480 min. = 300 pieces

\(Productivity=\frac{Net\;Production\;Obtained}{Standard\;Production\;Possible}\)

\(Productivity=\frac{300}{320}=\frac{15}{16}\)
