Question 1

A data entry clerk processes 120 records per hour with a 2% error rate. How many errors would be expected in a 7.5-hour shift?

Accepted Answer

18

Answer

Total records: 120 x 7.5 = 900. Errors: 900 x 0.02 = 18 errors expected in the shift.

Question 2

A code has the format: 2 letters followed by 4 digits followed by 1 letter (e.g., AB1234C). Which of the following is correctly formatted?

Accepted Answer

GH5678J

Answer

The format requires exactly 2 letters, 4 digits, then 1 letter (7 characters total). GH5678J matches: GH (2 letters) + 5678 (4 digits) + J (1 letter). ABC1234D has 3 initial letters, AB12345C has 5 digits, and A12345BC has 1 initial letter.

Question 3

Given the sequence: 3, 7, 15, 31, 63, what is the next number?

Accepted Answer

127

Answer

Each number is double the previous number plus 1: 3x2+1=7, 7x2+1=15, 15x2+1=31, 31x2+1=63, 63x2+1=127. Alternatively, each term is 2^n - 1: 4-1=3, 8-1=7, 16-1=15, 32-1=31, 64-1=63, 128-1=127.

Question 4

In a list of patient reference numbers, which one does NOT follow the pattern XX-NNNN-X (where X is a letter and N is a digit)?

Accepted Answer

GH-901-J

Answer

The pattern requires exactly 4 digits in the middle section. GH-901-J only has 3 digits (901), which does not match the XX-NNNN-X pattern. All others have exactly 4 digits in the middle.

Question 5

A typist types at 65 words per minute with 98% accuracy. In a 500-word document, approximately how many words will contain errors?

Accepted Answer

10

Answer

With 98% accuracy, 2% of words will contain errors. 500 x 0.02 = 10 words with errors.
