30.1%

Explanation:

Thymine (T) goes with Adenine (A).
Guanine (G) goes with Cytosine (C).

This means that the number of T and A is the same. And the number of G and C is the same.

If G is 19.9%, then C is 19.9%.

This means that together, G and C constitute 39.8% of the human DNA. The rest of the DNA (60.2%) is composed by T and A together.

Since the number of T and A is the same, half of 60.2% is T and the other equal half is A.

Hence, T = 30.1%.
