Percentage increases!!!

I have two datasets:

Code:

---

        A          B          C          D          E          F          G          H          I          J 
1        13%        21%        14%        27%        42%        74%        74%        76%        74%        82%
2        4173        3653        4335        7154        9891        10230        11664        19460        22059        23988

---

Now I want to find the the percentage increase / decrease between the current and previous values (e.g: A & B). Which of the following are correct?

1. Value B (21%) is 8% greater than value A (13%).
   
2. Value B (21%) is 62% greater that value A (13%).
   
3. Value B (3653) is 12% less than value A (4173).
   

Now if I want to compare the percentage increases between the values in dataset 1 and dataset 2 which scenarios do I use for the comparison to be correct from above; 1 and 3 or 2 and 3?

Value B (21%) is 8% greater than value A (13%).

It's not 8% greater, it's 8 units greater (and the units happen to be %), but 62% greater if you are comparing the two. If that makes any sense...

..and for your 3. Statement, Yes the Value B(3653) is 87,5% of the Value A(4173), therefor it 12,5% less then Value A (based on Value A as 100%)
