Answer: 11, 30

Step-by-step explanation:

Given

There were a total of 41 national battlefields and national memorials

Suppose there are $x$ national battlefields

So, national memorials are $3x-3$

The sum of the two must be 41

$\Rightarrow x+3x-3=41\\\Rightarrow 4x=44\\\Rightarrow x=11$

So, there are 11 national battlefields and $3\times 11-3=30$ national memorials.
