ANSWER
The rating of fuse is ,if the current is greater than the rated current then the fuse blows.
So if the rating is 10A, then it is the maximum current that passes through fuse.
If two such fuses are connected in parallel , the total current divides into two components where each can be maximum of 10 A. The maximum total current can be 20 A.
If they are connected in series,same current flows through each of them. The maximum current allowed would be the minimum rated current among the two fuses.So here the current rating will be 10A.
Hope it helps uh.
