Testing

We will use four values for testing

First Amount : 2,40,000

Expected Result:

0 (according to step 2)

Second Amount: 4,50,000

Expected Result:

(450000-250000)*10/100 (according to step 3)

=>(200000) * 1/10 => 20000

Third Amount: 6,50,000

Expected Result:

25000 + ((650000-500000) * 20/100)(according to step 4)

=>25000 + 150000 * ?

=>25000 + 30000=>55000

Fourth Amount: 12,00,000

Expected Result:

(25000 + 100000) + ((1200000-1000000)*30/100) (according to step 5)

=>125000 + (200000 * 3/10)

=>125000 + 60000=>185000
