Don't read this explanation, It is wrong. The next one is right. 
Answer C
1)
First Year profit = Second year profit + x
Second year profit = Third year profit + x
It is not possible to make an equation such as (Second year profit)/(Third year profit)
Thus INSUFF
2)
We are not interested in the profit between First and Third, Thus INSUFFI
If we put the information together, we know that the profit each year was (15,900-13,800)/2
First year 13,800
Second 14,850
Third 15,900
Now it is possible to find a solution.

I am sorry for the explanation above.
I have read the first statement so fast that I mistook first for second
Here is my error.
1)
First Year profit = Second year profit + x
Second year profit = Third year profit + x
Reading carefully now, after noticing that I get the wrong answer, I saw that the first statement says "was the same as the increase from the first year to the third year". So my second equation should be:
1)
First Year profit = Second year profit + x
First year profit = Third year profit + x
As x equals x
(First Year profit)/(Second year profit) = (First Year profit)/(Third year profit)
(Second Year profit)/(Third year profit) = (First Year profit)/(First year profit) = 1
SUFFIC.
2) Well , the second is the same explanation:
We are not interested in the profit between First and Third, Thus INSUFFI
Answer A
PS.: The first statement could be resolve even faster. Reading the statement and writing down in equation we have
1º/2º = 1º/3º
2º/3º = 1º/1º = 1, which means that the profit in the second year was exactly the same in the third.
Well, now it is right.
Sorry.
