Question

An employee has £4000 of salary tax free. The next £1500 is taxed at 10% the next £28000 is taxed at 22% any further amount is taxed at 40% which of these groups of numbers would fall into the same equivalence class?
a.£4800; £14000; £28000
b.£5200; £5500; £28000
c.£28001; £32000; £35000
d.£5800; £28000; £32000

Answer 1

Answer:

Explanation:

The classes will be as follows:

Class I   : 0 to £4000          => no tax

Class II  : £4001 to £5500   => 10 % tax

Class III : £5501 to £33500 => 22 % tax

Class IV : £33501 and above => 40 % tax

Select the values which fall in three different equivalence classes. Option ‘d’ has values from three different equivalence classes.

Answer 2

Answer:

The correct option is (d) £5800; £28000; £32000

Explanation:

The correct solution is d.

Because,

4000 tax free

Next 1500 = 10%

Next 28000 = 22%

Above rest = 40%

Now if suppose,

• The salary exists b/w 4000 - 5500, It will be taxed 10%

• The  salary exists b/w 5500 - 33500, I will be taxed 10% b/w 4000 -5500 and 22% on earnings b/w 5500-33500

• if assume the salary stands above 33500, I will be taxed 10% b/w 4000 -5500, 22% on salary b/w 5500-33500 and 40% beyond 33500.

• Thus, our equality categories become salary b/w 4001-5500,5501-33500 and above 33500.

Option d has all the values in b/w the range 5501- 33500.
