An employee has £4000 of salary tax free. The next £1500 is taxed at 10% The next &po..

Answer / nidhi

According to me , correct answer is d.
Because
4000 tax free
next 1500 = 10%
next 28000 = 22%
above rest = 40%
Now if suppose My salary is b/w 4000 - 5500, I will be
taxed 10%

Now if suppose My salary is b/w 5500 - 33500, I will be
taxed 10% b/w 4000 -5500 and 22% on salary b/w 5500-33500

Now if suppose My salary is above 33500, I will be taxed
10% b/w 4000 -5500, 22% on salary b/w 5500-33500 and 40%
above 33500.

Therefore, our equivalence classes become salary b/w 4001-
5500,5501-33500 and above 33500.
Option d has all the values falling in b/w the rance 5501-
33500.

Please let me know if I am wrong.
