I think that you forgot to give the picture of the circle along with the question. I am answering the question based on my research and knowledge.
The total unshaded part of the circle = (3/5 + 1/4)
= (12 + 5)/20
= 17/20
Now, the full circle can be considered = 1
Then
The total shaded part of the circle = 1 - (17/20)
= (20 - 17)/20
= 3/20
I hope that this is the answer that has actually come to your desired help.
