Base % of Total DNA A 20%
C
G 30%
T

Base % of Total DNA
A 35%
C
G 15%
T

First case:

C -> 30% and T -> 20%

Second case:

C -> 15% and T -> 35%

Explanation:

First of all you should know that if it is DNA, it's formed by two strands. Also, in DNA, the amount of A is the same as the amount of T. And the amount of C is the same amount of G.

So, if you have 20% of A, you will also have 20% of T.

And if you have 30% of G you will have 30% of C

I hope it's useful and that you understand it!
