ISQI Certified Tester Foundation Level — Question 82

A system is designed to accept values of examination marks as follows:

Fail: 039 inclusive -

Pass: 4059 inclusive -

Merit: 6079 inclusive -

Distinction: 80100 inclusive -
In which of the following sets of values are all values in different equivalence partitions?

Answer options

• A. 25, 40, 60, 75
• B. 0, 45, 79, 87
• C. 35, 40, 59, 69
• D. 25, 39, 60, 81

Correct answer: B

Explanation

Option B is correct because it includes values from all defined categories: 0 (Fail), 45 (Pass), 79 (Merit), and 87 (Distinction). The other options contain values that fall within the same equivalence partitions, thus failing to represent distinct categories.
