1. 
[tex] \frac{18000-15300}{18000} [/tex] x 100% 
= [tex] \frac{2700}{18000} [/tex] x 100%
= 15 %

2. 
27000 - ( 17/100 x 27000 )
= 27000-4590 = 22410


3. 
 [tex] \frac{100}{100-14,5} [/tex] x 47025
[tex] \frac{100}{85,5} [/tex]
= 55000


4.
120.000 - ( 33 [tex] \frac{1}{3} [/tex]% x 120.000 )
= 120.000 - 40000
= 80000


5. [tex] \frac{750000-562500}{750000} [/tex] x 100% 
= [tex] \frac{187500}{750000} [/tex] x 100%
= 25 %
