A flow process chart of the existing method at a Pune fabrication shop lists 20 activities: 8 operations, 5 transports, 3 inspections, 2 delays and 2 storages. In the proposed method, 2 transports are eliminated, 1 delay is eliminated, and 2 inspections are combined with operations (so these inspections no longer appear separately). What percentage of the original activities remain in the proposed method?

75% of the activities remain. Of the original 20, two transports, one delay and two inspections no longer appear as separate activities, so five are removed. That leaves 15 activities, and 15 divided by 20 gives 75%.

  2. B75%
  3. C65%
  4. D80%

Explanation

Activities eliminated: 2 transports + 1 delay + 2 inspections combined into operations = 5 separate activities removed. Remaining = 20 - 5 = 15. 15/20 = 75%. The 70% option wrongly removes 6 activities, and 80% removes only 4.
