Here, the Formula is: (final value-initial value) /initial value * 100.

When ever we see this type of problems we can do like this.
Just observe above graph no need to calculate last two years because those are negative sign.
35-25/35*100 = 28.57%.
Note: Follow this formula (initial value-second value)/initial value*100.
