A money order system is designed to calculate the
charge for a transfer.
- Amounts from 1 to 1999 are charged EUR 10.
- Amounts from 2000 to 5000 are charged EUR 15.
- Amounts below EUR 1 or above EUR 5000 are not
accepted. Assume that only integer values can occur.
Which of these sets of amounts covers all equivalence
classes?
Select one:
a. 0, 99-1-2000-4999, 99
b. 0-1999-2000-5000
c. 0-100-2000-6000
d. 1-2000-5001-10000
The question has 4 classes ( Less than 1, EUR 10, EUR
15, More than 5000), so check for data in all these class.
First Class (Less than 1) should have value less than 1
like 0, - ve integer
Second Class (EUR 10) should have value anything from 1
to 1999
Third Class (EUR 15) should have value from 2000 to 5000
Fourth Class ( More than 5000) should have value more
than or equal to 5001

to re-run a complete section of the tests. Which of the
following is correct?
