In a system designed to work out the tax to be paid: An employee has £4000 of salary tax free..

Answer / mads

The answer is c because £4000 + £1500+ £28000 is taxed 22%
anything over £33500 should be taxed at 40%. All other
answers are near the boundaries when you sum each salary
band together

Answer / mads

sorry I meant all other answers are not near the
boundaries. the boundaries in this case are £4000 and £4001.
then £4000+£1500 which is £5500 and £5501, then
£5500+£28000 which is £33500 and £33501. Your boundary test
cases should change your expected results.
