Civil Service Numerical Reasoning Test Speed and Accuracy Calculations

Question 1

A data entry clerk processes 42 records per hour with a 97% accuracy rate. In a 7.5-hour working day, how many records are processed correctly?

Accepted Answer

305

Answer

Total records = 42 x 7.5 = 315. Correct records = 315 x 0.97 = 305.55, which rounds to 305 (partial records are not counted as complete).

Question 2

Two teams are processing benefit claims. Team A processes 180 claims per day and Team B processes 220 claims per day. They start simultaneously on a backlog of 3,200 claims. How many working days will it take to clear the backlog?

Accepted Answer

8 days

Answer

Combined daily rate = 180 + 220 = 400 claims per day. Days needed = 3,200 / 400 = 8 days exactly.

Question 3

A caseworker resolves an average of 24 cases per week. If a new digital system increases productivity by 37.5%, how many cases will they resolve per week with the new system?

Accepted Answer

33

Answer

Increase = 37.5% of 24 = 0.375 x 24 = 9. New rate = 24 + 9 = 33 cases per week.

Question 4

An office receives post at 9:00 AM. It takes 15 minutes to sort, then each of the 4 team members processes letters at 8 per hour. If 96 letters arrive, when will all letters be processed?

Accepted Answer

12:15 PM

Answer

Sorting finishes at 9:15 AM. Combined processing rate = 4 x 8 = 32 letters per hour. Time to process 96 letters = 96 / 32 = 3 hours. Completion = 9:15 AM + 3 hours = 12:15 PM.

Question 5

A quality check reveals that 18 out of 450 processed forms contain errors. What is the error rate, and how many errors would you expect in a batch of 2,000 forms at the same rate?

Accepted Answer

4% error rate; 80 errors

Answer

Error rate = (18 / 450) x 100 = 4%. Expected errors in 2,000 = 4% x 2,000 = 80 forms with errors.
