Answer:

20%  

Step-by-step explanation:

We can solve this with the rule of three.

If 100% represents 10 records, what percentage would be for 12 records?

 

So, if we subtract , it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.
