Question

Citizens of No-man’s-land are required to renew their passports every 10 years. For passport renewal, they have to collect a set of documents that they then send to the country’s capital. The average time in the mail is about 2 days. It takes 4 days before a clerk in the capital looks at the passport renewal. This takes about 10 minutes. The clerk then asks his assistant to prepare a form that is sent to the government’s printing office. The assistant completes this task within 3 days and it takes another 2 days in transit to the printing office. There, the dossier waits an average of 10 days before the new passport is printed, an operation that takes about 2 minutes. It is then sent back to the citizen, which typically takes another 2 days. What is the percent value-added time in this flow? 24 hours per day is the potential work time.

Answer is Option B - 0.0362%

Work:-

Total time = time for mail + time for wait before the clerk takes a look + Looking time + form completion time + transit time + wait time + printing time + receiving time

= 2 + 4 + (10 / 60 x 24) + 3 + 2 + 10 + (2 /60 x 24) + 2

= 23.00833 days

value added time = Looking time of clerk + Printing time = 0.00833 days

Fraction value added time = 0.00833 / 23.00833

= 0.0003622

Percentage Value added time = 100 x 0.0003622

= 0.0362%
