By what percent must 10 be increased to 25?

 

Is it 25% or 125%?

It is NEITHER !!!.

 

Write this rule down for the future:

 

25/10 =2.5 - 1  x  100 =1.5  x  100 = 150% increase.

If we increase 10  by 100%....we effectively double 10  = 20

 

If we increase 10 by 150%....we add  15 to 10   = 25

 

So.....150%

 

 

cool cool cool
