20 is what percent greater than 16?


Sagot :


considering 'x' is the increase then

20 = 16 (1 + x)  ----(1+x) since we are to consider that 16 is 100%  to find the actual percentage of which 20 is greater than 16

20 = 16 ( 1 + x)

20 = 16 + 16x

20 - 16 = 16x

4 = 16x

x = 4/16

x = 0.25

Therefore 20 is greater than 16 by 25%


The percent increase would be computed as:
(20-16)/16
= 4/16
= 1/4
= 0.25 

Therefore 20 is 25% greater than 16
